Since we're dealing with trig functions, we can try with different angles as input, such as: $0^{\circ}, 30^{\circ}, 60^{\circ}, 90^{\circ}, 180^{\circ}...$
Learn how to solve differential calculus problems step by step online. Prove that ((1+sin(x))/(cos(x)+1-sin(x)))/sin(x)=2sec(x) is not an identity. To prove that an equation is not an identity, we only need to find one input at which both sides of the equation result in different values. If we try with the following value. After substituting the value and simplify on the left side, we get. After substituting the value and simplify on the right side, we get.
