simplify 1/(cos(x))*1/(cos(x))

simplify

\frac{1}{cos ( x )} \cdot \frac{1}{cos ( x )}

sec^{2} (x)

Solution steps

\frac{1}{cos ( x )} \cdot \frac{1}{cos ( x )}

Use the basic trigonometric identity:

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

= sec (x) sec (x)

Apply exponent rule:

aa = a^{2}

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

= sec^{2} (x)

sin^{3} (a) + sin (a) cos^{2} (a)

\frac{x ^{2} - 3 x - 40}{x ^{2} - 8 x}

\frac{2 10}{5}

(5 x y^{2} + 3 x^{2} - 7) + (3 x^{2} y^{2} - x y^{2} + 3 y^{2} + 4)

(\frac{2 ^{5}}{2 ^{3}})^{2}
