I am doing sum and difference formulas with sin, cos, and tan. I am doing tan75 with the difference formula. So tan 120-45 I have all the things found I just don't know...

During a polar vortex last winter, the temperatures followed a regular pattern each day for a week: the maximum temperature was –4° F each day at 5:00 pm and the minimum temperature each day was –...

cos-1(cos(47pi/12) arcsin(tan(-pi/6)) csc-1(cos(2017pi/2018)) cot(arcsin(1/2 csc(-11pi/4)))

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

A guy wire whose grounded end is 16 ft from the pole it supports makes an angle 56 degrees with the ground. How long is the wire.

A boat sails on a bearing of 75° for 128miles and then turns and sails 203miles on a bearing of 191°. Find the distance of the boat from its starting point. I am unsure how to solve...

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...

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...

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...

(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.

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

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)

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

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

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

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...
