Question

sec²theta-1×cosec²theta-1=1​

Answer 1

Answer:

sec*2theta-1 can be written as tan*2theta and 1-cosec*2 theta can be written as -cot*2theta

tan*2theta×(-cot *2theta) is equal to -1

Answer 2

• sec^-1×cosec^-1
• tan^× cot^. sec^-1= tan^, coswc^-1= cot^
• taking square root
• tan× cot.
• sin/ cos× cos/ sin
• 1
