Question

If cosθ + secθ = 2, then find the value of cos²θ+sec²θ.​

Answer 1

Answer:

zero

Step-by-step explanation:

by using the algebraic identity a²+b²= (a-b)²-2ab you will get ( cos theta + sec theta) - 2costhetha sectheta.....

substitute the value of cos thete + sec theta for 2 then write sec theta in the form of 1/cos theta...then solve to get zero...

hope this helps you matey!!!!
