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...

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)

(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.

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

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...

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

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

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...

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....

find all the solutions of the given equation in the interval 0≤x<2pi

(tanv+1)^2(tanv-1)^2=2sec^2v

Having trouble with these two problems... Verify each identity sin2 x/2=csc x-cot x/2 csc x 2tan x/2=sin2 x +1 - cos2 x/sin x (1+ cos x)

Use a graphing calculator to approximate, to three decimal places, the solutions to the equation. If there is more than one solution write them separated by comas.

This is for my trig class. Thanks for the help!

A. sin22.5 degrees and B. tanpi/12 degrees
