" (iv) "(sin theta+cos theta)(tan theta+cot theta)=sec theta+cosec theta

What is ((sin theta +cos theta)(tan theta +cot theta))/(sec theta + cosec theta) equal to ?

" (2.) "tan theta+cot theta=sec theta cosec theta

Which of the following pairs may represent the eccentricities of two conjugate hyperbolas, for alpha in (0,pi//2) ? a. sin theta, cos theta b. tan theta, cot theta c. sec theta, "cosec"theta d. 1+sintheta,1+cos theta

Which of the following pairs may represent the eccentricities of two conjugate hyperbolas, for alpha in (0,pi//2) ? a. sin theta, cos theta b. tan theta, cot theta c. sec theta, "cosec"theta d. 1+sintheta,1+cos theta

Prove the following identity : (sin theta+ cos theta) (sec theta+ cosec theta) =2+ sec theta cosec theta .

Prove the following identity : (sin theta)/(1+cos theta)+ (tan theta)/(1+cos theta)= sec theta cosec theta- cot theta .

Prove the identity ("sin"theta+"cos"theta)("tan"theta+"cot"theta)="sec"theta+"cosec"theta

tan theta/(1-cot theta)+cot theta/(1-tan theta)=1+sec theta cosec theta

tan theta/(1-cot theta)+cot theta/(1-tan theta)=1+sec theta cosec theta

tan theta/(1-cot theta)+cot theta/(1-tan theta)=1+sec theta cosec theta
