Question

if sin theta is equal to cos theta then the value of 2 tan theta+cos square theta is​

Answer 1

Answer:

5/2

Step-by-step explanation:

sin a  = cos a

=> tan a = 1

=> a = 45°

expression to calculate:

2 tan a  +  cos² a

= 2 tan45° + cos²45°

= 2 × 1 + (1/√2)²

(tan 45° = 1, cos 45° = 1/√2)

= 2 + 1/2

= 5/2

Answer 2

$\huge { \boxed {\red{given}}}$

sin=0 cos 0

possible for only one set

$0\pi \:/ 4$

now required value : 2tan0+cos²0

2 tan 45°+Cos²45°

5/2
