If sin(x) = 1/4 and x is in quadrantI,find the exact values of the expressions without solving for x. (a) sin(2x) (b) cos(2x) (c) tan(2x)

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

This is for my trig class, thanks for the help! If you could, could you please show all your work? Thanks again!

This is my work. tanx = -2sinx sinx/cosx = -2sinx sinx = -2sinxcosx (multiply by cosx) 1 = -2cosx (divide...

Given that sin(a)=2/3 and cos(b)=-1/5, with a and b both in the interval of pi - pi/2

a) tan^2(theta)+cos^2(theta) b) 2tan(theta)cot(theta) c) 2cot^2(theta)-1 d) sec^2(theta)+csc^2(theta)

Prove sec2x-1=sec2xsin2x, justify significant steps. (state identities used)

Please help me answer the following question! I'm stuck! Prove that cos6ß + sin6ß = 1/4 + 3/4cos2ß I've tried simplifying out the LHS into (cos2ß)3 + (sin2ß)3,...

verify the trig identity plz help!!!

Using Pythagoras, and making reference to a right angle triangle.

sinh x = (e^x-e^-x/2) and cosh x = (e^x + e^-x/2)

1) 2sec x =4.6 2) 3cos^2 x + cos x-2 =0 3) Sech x =0.554

Prove sin4z = [4tanz(1-tan2z)]/(1+tan2z)2

a) (sinx-tanx)/(cosx-cotx)=〖tan〗^2 x((cosx-1)/(sinx-1)) b) (cos^2x-sin^2x)/sinxcotx-cosxtanx)= cosx + sinx Please show work. Thank you so much!

Verify the Identity.

Using angle A=53.13 and angle B=36.87 find an algebraic expression for tan theta =tan (a-B) in terms of x. x= 12 m

I need some help with the steps to solving this, I know that I need to foil out the problem but I need to get a numerical value for the expression.

I need to set the problem sides equal to each other. A step-by-step guide would be helpful. My entire class doesn't understand it.
