The first derivative of f is given by LaTeX: f'\left(x\right)=\frac{\cos^2x}{x}- \frac{1}{5}f ′ ( x ) = cos 2 ⁡ x x − 1 5. How many critical values does f have on the open interval LaTeX: \left(0,10\right)( 0 , 10 )? Enter an integer value and 0 if no critical values.

1/4 because there is 4 grades.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
