# true or false questions:

a)The derivatives of the reciprocal trigonometric functions can be found using the chain rule and their related base functions.

b) A sinusoidal function can be differentiated only if the independent variable is measured in radians.

c) There are an infinite number of tangents with a given non-zero slope to a sinusoidal curve.

d) The graph of a power function y=x^n is steeper than the graph of an exponential function, y=a^x (a>0, a doesn't= 1), as the value of x increases.

e) The derivative of an exponential function is always another exponential function.
