simplify 3/(cos^2(3x+5))

simplify

\frac{3}{cos ^{2} ( 3 x + 5 )}

3 sec^{2} (3 x + 5)

Solution steps

\frac{3}{cos ^{2} ( 3 x + 5 )}

Use the basic trigonometric identity:

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

= 3 sec^{2} (3 x + 5)

\frac{d}{d t} ((t + 3)^{\frac{2}{3}} (2 t^{2} - 3)^{3})

f (t) = 5 t - 9 t^{2}

\frac{\partial}{\partial x} (x^{2} - x y + y^{2} + 3 x - 2 y + 1)

y^{2} = 2 x y y^{^{'}}

x \to - 1 lim (2)
