Locate each point in a coordinate system. Draw a ray from the origin through the given point. Indicate with an arrow the angle in standard position having smallest positive measure. Then find the distance r from the origin to the point, using the distance formula. (4√3, -4)

Using the exact value cos(pi/4) = 1/square root of 2 and a trigonometric formula, show that sin (pi/8) = (square root of (2 - Square root of 2)/2. Using exact value cos(pi/6) = (square root of 3)/2 and a double angle formula to obtain an expression for the exact value of sin(pi/12)

In the attached problem I need to solve for the unknown angle Beta. The book calls it a type IV problem and gives the procedure on how to solve for a type IV problem. I have tried to solve this problem but with no luck. I have attached the problem, the procedures to solve for the type IV and the formulas and pictue of a type I

Solve this trigonometric equation for x where 0<x<2pi 2sin^2x + 3cos x = 0

This triangular pyramid is a type II as the book puts it. Three faces are right triangles and the 4th in a diagonal plane is an oblique triangle. The book explaines that if the angle to be found is in the oblique triangle you should solve for an auxilliary angle in the third right angle which lies at the same vertex as the requi

Let ABC be a triangle. Prove that (cos(A/2))^x, (cos(B/2))^x, and (cos(C/2))^x are the lengths of a triangle for any x greater than or equal to 0. From what I have found in my books, it is impossible to solve for side lengths of a triangle using AAA b/c there is no formula to do so. It is possible to find similar triangles
