`tan(picostheta)=cot(pisintheta)`

If tan(pi.costheta)=cot(pi.sintheta), then: cos((pi)/(4)-theta)=..... (a) 1/2 (b) 1/sqrt2 (c) 1/(2sqrt2) (d) sqrt2/2

If sin(picostheta)=cos(pisintheta) , then the value of cos(theta+pi/4)=

If sin (picostheta) = cos (pisintheta) , then show that, theta = +-1/2sin^(-1)(3/ 4)

If pisintheta=1,picostheta=1 , then the value of {sqrt(3)tan((2)/(3)theta)+1} is

(cot theta)/(cot theta-cot3 theta)+(tan theta)/(tan theta-tan3 theta) is equal to

Prove : (tan theta) /(1- cot theta) + (cot theta)/ (1-tan theta) = 1 + tan theta + cot theta

(cot theta)/(cot theta-cot3 theta)+(tan theta)/(tan theta-tan3 theta) is equal to:

tan A-cot A=-2cot2A
