Question

if
tan theta = cot theta, then the value of 2 sin theta + cos² theta ​

Answer 1

Answer:

tan theta = cot theta

only when theta is 45°

therefore theta = 45

2sin 45 + cos²45

$2 \times \frac{1}{ \sqrt{2} } + \frac{1}{2}$

$\frac{2}{ \sqrt{2} } + \frac{1}{2}$

$\frac{2 + 1}{2 \sqrt{2 =} }$

$\frac{3}{2 \sqrt{2} }$
