Question

(1-cos2Q) Sec2Q=tan2Q prove​

Answer 1

Answer:

because 1-cos=sin and sec=1/sin so sin or sin cut hoo jaige

Answer 2

Step-by-step explanation:

(1-cos²Q)sec²Q= tan²Q.;

LHS: (1-cos²Q)sec²Q;

=sin²Q*sec²Q; //sin²x = 1 - cos²x.

= sin²Q(1/cos²Q); //secx= 1/cosx.

=(sinQ/cosQ)²;

= tan²Q; //(sinx/cosx)=tanx.

=RHS (proved)
