`sin(-theta)=........`
`(a) cosectheta`
`(b) -cosectheta`
`(c) sintheta`
`(d) -sintheta`

Slove : sin9theta =sintheta

Solve: sin4theta=sintheta

If sintheta + cosectheta = 2 then sin^6theta + cosec^6theta is..

If sintheta + cosectheta = 2 then sin^6theta + cosec^6theta is..

If cosectheta+cot theta=7 , then find tantheta .

Prove that d/(dx)(cosectheta)=-cosecthetacottheta.

sin.theta. cosec theta= …..

The value of (2(sin2theta+2cos^2theta-1))/(costheta-sintheta-cos3theta+sin3theta) is adot costheta b. sectheta c. cosectheta d. sintheta

(i) "sin"theta cot theta + "sin"theta cosectheta = 1+ costheta (ii) sectheta(1-"sin"theta) (sectheta+tantheta)=1 (iii) "sin"theta(1+"tan"theta)+costheta(1+cottheta)=sectheta+cosectheta

int(cosec theta-cot theta)/(cosectheta+ cot theta)d theta=
