SHOWS EVALUATION OF TWO TRIGONOMETRIC EXPRESSIONS AND THEN SHOWS THE USE OF THE ADDITION FORMULA USING THE GIVEN FUNCTION VALUES

This is translated from a trigonometry problem in another language, I hope you understand it.

Posted a question earlier then found the original question which apparently had more info, nned help solving. Heres the question: The 180lb. man climbs up the ladder and stops at the position shown...

Solve the given equation over the interval [0,2): 2sinx+ (sqrt 3) sin^2x=-(sqrt 3) cos^2x A. x=0, and x=(pi/2), and x=(3 pi/2), and x=2(pi)x=(3 pi/2), and x=(7 pi/2) b. x=(4 pi/3) and...

My math is online and the helper says that sin∅= y/r= (5√74)/74 = 144.5° . how do u convert that fraction into degrees. I did try the inverse of ∅=sin-1(y/r) , but for my example that...

You have a right triangle and the hypotenuse is 10 and adjacent side is 6 and the opposite side is 8, this is what the triangle looks like except NO cm! http://www.cimt.plymouth...

The displacement function d(t) is a combination of functions: d(t) =5 f(t)g(t)+r. Consider the following situation: • The mass is at a resting position of r = 30 cm. • The spring provides a period...

Find the angle x such that 0 is less than or equal to x which is less that 2pi. cos(2x)= =2-2sin^2x

given sin(x)= -3/5, pi<x<3pi/2; cos(y)= 12/13, 3pi<y<2pi find exact value of: a) sin(2x) b) cos(y/2)

a) sin50cos10+sin10cos50= b)sin75+sin15= c) sin105= d) sin(5pi/24)cos(pi/24)

cotx=-√3, cosx<0, tanx(x-Π/6) find the exact value

(cos (11π/15) cos (π/10)) - (sin (11π/15) sin (π/10)) (p.s. π = pi) Please don't give a decimal as the answer. I need the exact answer.

The US Air Force was running maneuvers with the F22 Raptor, flying low enough so that you could see the shock cone created as the jet flies overhead at supersonic speeds. You wanted to take a video...

verify that: cos^3(x)+sin^3(x)=1/2* (cos(x)+sin(x))*(2-sin(2x))

Show that if α, β and γ are the angles of a triangle, then we would have but tanα+tanβ+tanγ=tanαtanβtanγ I need help with this. I've been trying but getting nowhere. Thanks....

I thought it could possible be solved by a double angle formula, but I cant seem to make it work
