`lim_(theta-gtpi/4)(1-tantheta)/(1-sqrt(2)sintheta)`

evaluate lim_(thetararrpi/4)(sqrt2-costheta-sintheta)/(4theta-pi)^2

evaluate lim_(thetararrpi/4)(sqrt2-costheta-sintheta)/(4theta-pi)^2

evaluate lim_(thetararrpi/4)(sqrt2-costheta-sintheta)/(4theta-pi)^2

If 0 leq theta leq pi and sin(theta/2)=sqrt(1+sintheta)-sqrt(1-sintheta) , then the possible value of tan theta is (a) 4/3 (b) 0 (c) -3/4 (d) -4/3

(tantheta)/sqrt(1+tan^2theta) = ………………

If tantheta=(8)/(15) , the value of (sqrt(1-sintheta))/(sqrt(1+sintheta)) is :

Prove that sqrt((1+sintheta)/(1-sintheta))+sqrt((1-sintheta)/(1+sintheta))= 2sectheta=2 sec theta

Evaluate: int(tantheta)/(1-sintheta)d theta

For pi/2

If theta=240^@ is the following statement correct? 2sin\ theta/2=sqrt(1+sintheta)-sqrt(1-sintheta)
