derivative of y=(1/(cos^2(x)))

\frac{d}{d x} y = (\frac{1}{cos ^{2} ( x )})

y = tan (x) + c_{1}

Solution steps

\frac{d y}{d x} = (\frac{1}{cos ^{2} ( x )})

f^{^{'}} (x) = g (x)

then

f (x) = \int g (x) d x

y = \int \frac{1}{cos ^{2} ( x )} d x

\int \frac{1}{cos ^{2} ( x )} d x = tan (x) + c_{1}

y = tan (x) + c_{1}

x \to - 9 lim (\frac{8 x + 72}{∣ x + 9 ∣})

\frac{( 2 \cdot s )}{s ^{2} + 6 s + 13}

\frac{d}{d θ} ((- 1 + cos (θ)) sin (θ))

\int x^{4} (3 x^{5} + 1)^{9} d x

\frac{d}{d x} (∣ x - 8 ∣)
