Step-by-step explanation:
We know that sin x is the inverse of cosec x. Also, minimum value of function t+(1/t)=2. So, minimum value of sin x + cosec x should equal 2. Here, I will also prove how t+(1/t) has minimum value 2. Note that AM and GM stand for arithmetic mean and geometric mean respectively. We are concerned about AM and GM of t, 1/t.
