4 sin x cos x - 2√3 sin x - 2√2 cos x +√6=0 interval 0≤x<2pi

4 sin x cos x - 2√3 sin x - 2√2 cos x +√6=0 interval 0≤x<2pi

There are 2 possible answers I can choose from. Either Bounded or Continuous

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

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)

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

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

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

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)

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.

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.

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

Use the trigonometric identities to write each expression in terms of a single trigonometric function. A. Sin^2 D. (tan^2 +1)Sin^2 Cos^2 B. cot +1 E. 1+ 1 tan +1 cot^2 C. Sin^2 +cos^2...
