Jul 26, 2021 ... Assume that playing soccer requires 540 calories per hour. On a particular day, you ate 2,000 calories in food. You played soccer for 2.5 hours. Solve for a variable, factor, expand, evaluate fractions, linear equations, quadratic equations, inequalities, systems of equations, matrices. Dec 10, 2016 ... Verify the Identity. csc(x) - cot(x)/sec(x) - 1 = cot(x) csc(x) - cot(x)/sec(x) - 1 = 1/sin(x) We have cot 3x = cot (2x+x). ⇒(cot 2x cot x)-1cot 2x + cot x. ∴ cot 3x (cot 2x+ cot x)= (cot 2x. cot x)-1. ⇒ cot 3x . cot 2x+ cot 3x . cot x = (cot 2x . cot x) ...
