Verify sinx cscx = 1

can you please tell me how to work out all types of angles like z and f angles etc at a level f basis

Hi their, I am revising for my gcse exam in 5 weeks and a few topics that I'm struggling with is Circle Theorems and Trigonometry and so if anyone could help me I would be very grateful. Thank you so much!!!

if sin data =2/5 what is the exact value of cos 20?

The midpoints of the sides of triangle ABC are (4,1) , E (-2,3) , F ( 1,-4). Use analytic geometry to calculate the coordinates of the vertices of triangle ABC

http://www.flickr.com...mysterious-midnight/ theres the two questions please help

I'll attach the question with this.

We have to verify the identity by baisically showing all the in between process. You have the problem, and you have the solution, its just the how get ther by baisicallt transforming the different parts.

Ex. (tanX-secX)2=1-sinX/1+sinX

how do you do trigonometry?

how do you find out the area of a uninformed triangle

pleaseits for my maths home wrok and i am confused!

How do you work out an angle on a straight line?

I think i am really stuck on angles and i really need an online tutor

How do you work out the area of a right-angled triangle?

how does defining the types of angles

if angle 4 equal 5n+64 degrees and angle 1 equal 4n=35 degrees

What is the sum of the interior angles of a polygon with 9 sides?

You have an isosceles triangle with an area of 50cm and AB=BC=10cm. How many degrees is angle ABC?

please help i really dont understand this one question

i want to know the what the meaning of the letters:Z F C for angles and what the degrees are for them if that makes sense 🙂

A truck of weight 28,000 pounds is parked on a 11degree slope. Find the magnitude of the resultant force.

The triangle shown in the figure is a right triangle with one vertex on the graph y = f(x), where f(x)=8sqrt(x). Express the angle θ as a function of x, where 0

there's a link to the graph. http://www.webassign.net/...439e53dfb025a29.gif

how do we prove that tan^-1(x) + cot^-1(x) = pi/4 ?

What quadrilateral has four 90 degree angles, but not all sides are congruent ?

Can someone please explain the sine and cosine rules please, would help a lot as I haven't really grasped the concept of them.

11 and 13 I am having huge trouble with.

11 is a triangle inside a triangle. Smaller one being 50° larger being 35° and the base of 35° is 10m. Joanne has to replace the two supporting guy wires for a hydro pole. She measures the distance between the base of the wires to be 10m, and their angle of inclination to be 50° and 35°. Determine the total length of the guy wire that needs to be replaced. Determine the height of the pole.

Question 13 is: From his nest, Mr. Robin flies east for 80m then south for 60m and then straight up into the sky for 30m. At this point how far is Mr. Robin from his nest? And at what angle of elevation viewed from their nest does Mrs. Robin see Mr. Robin?

Define and explain what is the sum of all angles (in degrees) of a triangle?

Hi, I need some help with this trig. The question is "The area of triangle ABC is 8. If the length of BC is 1/4 the length of AB, then AC equals what?

Finding a value for a trig equation

The function f is defined for all real numbers by f(x)=sin(2x+ π/4) Find the general solution of the equation f(x)=0.

I seriously need help with this!!!

Hi, could you please explain to me what the deal is with SOH CAH TOA in trigonometry?

Hi, could you please explain to me what the deal is with SOH CAH TOA in trigonometry?

what is a isosceles triangle

what is the area for a triangle if the base is 10m and the sides are 20m?

I need to find out what degree an obtuse and acute angled triangle is. Like you know how a right angled triangle is always 90 degrees well can you help me find out what an acute and obtuse is between ..thanks i need to know tonight as my homework has to be in tomorrow morning . thanks agian

What is trigonometry?

ABC is an isosceles triangle, these are the lengths of the sides: AB= 4a+3, BC=2b+5, AC= 2a+b The perimeter of the triangle is 32 cm, find the values of a and b. I don't just want the answer I want to know how to get to the answer 🙂

I just dont get it
