Angles ∝ and β are the two acute angles in a right triangle. use the relationship between sine and cosine to find the value of ∝ if ∝ > β. sin( 5x 3 + 20) = cos( 2x 3 + 14)

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
