cot θ= 2x/ 2y+ gt2 Where θ is the angle of elevation (in degrees) of the launcher and g=32.3 ft/s2 The NDB water ballon team is firing at the Mercy Team...

If Sin∅+cos∅=√2,then evaluate:tan∅+cot∅

Let z= tan a/2 Show sin a= 2z/1+z2

(f(x+h)-f(x))/h= (sin (x+h)-sin x)/h= (sin x)((1-cosh)/2)

A first approximaition to the sawtooth curve is given by: y= 1/2sin 2pi x + 1/4 sin 4pi x Show that y=sin (2pi x) cos2(pi x)

tan (θ+ pi/2)= (tan θ + tan pi/2)/(1-tan θ tan pi/2)= (((tanθ)/(tan pi/2))+1)/ ((1/tan pi/2) -tan θ)= (0+1)/ (0-tan θ)= 1/ -tan θ= - cot θ

can u compress (x-8)squared + (x+8)squared

A.) sec θ−cos θ/sec θ = sin2θ B.) csc x − sin x = cos x cot x

Hello! I am having some trouble verifying a trig identity sin(4x)=4cos^3(x)sin(x)-4sin^3(x)cos(x)

Its options are a)11 b)3 ...

2cosx - secx = cosx - tanx/cscx

Simplify the following trig expression : 1/1-sec x - 1/1+sec x

Can someone walk me through each step with an explanation? please?

How do you verify the identity?

prove (1 - cos2x)(1 - tan2x) = sin2x cos2x/1-sin2x I can't seem to solve this! Halp!!!

Verify the Identity cot2(x) − tan2(x) = csc2(x) − sec2(x)

Prove sin4x = 4 (sin x-2 sin^3 x)/secx I can't seem to solve this! Halp!!!

prove the following identity. 1-cosθ/sin2θ = 1/1+cosθ thanks!

I don't find an answer for this question matching the solution, please help me out! I need to get exact values for this, solved by solving the equation. The range is 0 to 2π Solve...
