Question

If sin theta is equal to cos theta then find the value of 2 tan square theta+ cos square theta

Answer 1

Answer:

Step-by-step explanation:

let the angle be 'A'

   given is

   sin A=cosA

=>p/h=b/h

=  p=b

h=√p²+b²=√p²+p²=√2p²=p√2

now ,

        tan²A=[p/b]²=1     [p=b]

        cos²A=[b/h]²=[1/√2]²=1/2

     =>1+1/2=2+1/2=3/2
