Use trigonometric identities to find the exact value of tan(5π/8).
Use trigonometric identities to find the exact value of cos(5π/8).
a) -1/3 b) 1/3 c) - sqrt1/6 d) sqrt1/6 I think it is either c or d. I'm confused on whether it is negative or positive. If it is in quadrant 4, wouldn't y be...
Find the exact value of cos(11p/8) A) √(2+√2)/4 B) √(2-√2)/4 C) - √(2-√2)/4 D) -√(2+√2)/4 I think it is either c or b To...

1Alltrigonometric equations are identities. true or false? My answer: false 2 cos a/2= +/- √(1-cosa)/2 True or false? False...
tan^2x+sec^2x=1 true or false? for all values of x 2) cos2a=2cos^2a-1 for ALL values of a true or false? 3) sin(-x)=-sinx for all values...
tan^2x+sec^2x=1 true or false? for all values of x Uhm I think false? tan^2 x+1=sec^2x. So to get 1 on the other side of the...
sin theta + sin 3 theta = tan theta sec theta Show that the right side equals the left side
please show me any steps you are able to
establish identity 1-cos(2x)=tan(x)sin(2x) (1+cosθ)tan θ/2 =sinθ
The Value (5π)/4 is a solution for the equation 3√2cscθ+5=-1 true or false Please explain this to me? there is no solution to the equation secx=0 true...
