Trigonometry

Develop the solutions for the following problems: 1.) Graph the function y = -1 + 2sin(x + π) over a 2-period interval. a. What is it's period? b. What is its amplitude? c. What is it's range? d. What is the y-intercept of it's graph? e. what is it's phase shift? 2.) The formula for the up and down motion of a weight on a spring set in motion is s(t) = a sin √k/m t If the spring constant k is 6, what mass m must be used to produce a period of 1 sec. Hint: period = 2л/w

Trigonometric Identities

If you would please give me each step to solve these problems so I can get a better understanding how to solve these types of problems would be very helpful. Thanks. Graph each expression and use the graph to conjecture an identity. Then verify your conjecture algebraically. 1. sec x - sin x tan x The answer to this problem is sec x - sin x tan x = cos x. How did they come up with this answer? Verify that each equation is an identity. 1. tan^2 x - sin^2 x = (tan x sin x)^2
