please do step by step, I need help understanding not just the answer

Is the following a function? (type yes or no) y = 2 sin x What is the slope of the tangent line at x=30 degrees? Is the tangent line increasing or decreasing? (type increasing or decreasing)Is the following a function? (type yes or no) sec x - 2 cos x What is the slope of the tangent line at x=60 degrees? (use asqrt(b) for example 2sqrt(7) ) Is the tangent line increasing or decreasing? (type increasing or decreasing) You need to attach a graph of the function along with its tangent line on the same page to your step by step submission
