explain how to do this

Ok, so parentheses first, you'd do thirty six minus four. Take that answer and rewrite it in parentheses. then you'd do exponents. Which is seven to the second power. you'd do seven times seven. you'd replace that where you're exponent is. So it'd look like (32÷16)-49.

Sin(a)+cos(a)+cot(a)-1=2(csc(x)+1)
