[-10,0] The range is the set of all possible y values. a sinx + b cosx can be rewritten as sqrrt (a^2 + b^2) cos (x - tan b/a) So this equation can be written as 5 cos (x - tan 3/4) - 5. The phase ...
We can rewrite the equation as: sin^4x + cos^4x = 1. Take note that cos^4x = (cos^2x)^2. So, we will have: sin^4x + (cos^2x)^2 = 1. Using the identity sin^2x + cos^2x = 1, we will have: cos^2x = 1 ...
(sinx-cosx)(sinx+cosx) Factorizing this algebraic expression is based on this property: a^2 - b^2 =(a - b)(a + b) Taking sin^2x =a and cos^2x=b we have : sin^4x-cos^4x=(sin^2x)^2-(cos^2x)^2=a^2-b^2 Ap
4, Expand in terms of complex exponentials. sin4x + cos4x = (eix − e − ix 2i)4 + (eix + e − ix 2)4, Notice that i4 = + 1, so we get, sin4x + cos4x = 1 16(2e4ix + 2e − 4ix + 12) where we use the relati

tan x = sin x cos x = 4. This determines sin x and cos x (up to a common sign), and these can be computed with a reference triangle. In any case, the ambiguity in the sign disappears when we form the

f (x) = sin⁴x + cos⁴x. f (x+π/2) = sin⁴ (x+π/2) + cos⁴ (x+π/2) f (x+π/2) = sin⁴x + cos⁴x. f (x+π/2) = f (x) it's value repeat after every kπ/2, where k is positive integer. So period of function is π/
Cite. (-sinx)^4 + (c0sx)^4 = 1. we know that sinx = -sinx. ==> (sinx)^4 + (cosx)^4 =1. Complete the square: ==> (sin^2 x + cos^2 x)^2 - 2sin^2 x cos*2 x =1. ==> But we know that sin^2 x + cos^2 x ...
