simplify (cos(2x))/(cos^2(x))

simplify

\frac{cos ( 2 x )}{cos ^{2} ( x )}

sec^{2} (x) cos (2 x)

Solution steps

\frac{cos ( 2 x )}{cos ^{2} ( x )}

Use the basic trigonometric identity:

\frac{1}{cos ( x )} = sec (x)

= sec^{2} (x) cos (2 x)

\frac{8.9 - 9}{8.9 - 3}

3 x - 2 y (4)

\frac{2}{3} \div \frac{5}{8}

15 x - 2 x - (13 x + 10 x)

1 0^{5} \cdot 1 0^{3}
