The value of x which will satisfy the equation:
x×cos(a)×cos(90∘−a)×tan(90∘−a)×sec(a)×cosec(a)×tan(a)=1 is
As, cos(90∘−a)=sin atan (90∘−a)=cot aSo, x×cos(a)×cos(90∘−a)×tan(90∘−a)×sec(a)×cosec(a)×tan(a)=1⇒x×cos(a)×sin(a)×cot(a)×sec(a)×cosec(a)×tan(a)=1⇒x×(cos(a)×sec(a))×(sin(a)×cosec(a))×(cot(a)×tan(a))=1⇒x×1×1×1=1⇒x=1
