If sec thita+tan thita is equal to P, then find the value of cosec thita |
|
Answer» I/cos thethe+ sin thethe / cos thethe1+ sin thetha/ cos thethe=pCosecthetha= 1/ sin thethaSecthethe + tanthethe= p..................1Sec^2+tan^2=1(Secthetha-tanthethe) ( secthetha+ tanthetha)( secthetha- tanthethe)=1.................2By adding equation 1 and 22secthetha= p+1/pSectheta=p^2+1/2p(P^+1)-(2p)^2Under root (p^2)^2+1^2×2p^2-4p^2Under root p^4+1-2p^2Root cancel by squareP^2-1Cosecthetha is hypho/ parpendicularSo Cosecp= p^2+1/p^2-1 Ha, bahut common question hai (P^2+1)/(p^2-1) |
