limit as x approaches pi of ln(cos(x)-4)

x \to π lim (ln (cos (x) - 4))

Does not exist

Solution steps

x \to π lim (ln (cos (x) - 4))

x \to a - lim f (x) = x \to a + lim f (x) = L

then

x \to a lim f (x) = L

x \to π - lim (ln (cos (x) - 4)) =

Does not exist

x \to π + lim (ln (cos (x) - 4)) =

Does not exist

= Does not exist

y^{^{''}} - 4 y^{^{'}} - 12 y = sin (2 t)

\int \frac{2 x + 3}{( x ^{2} + 3 x + 1 ) ^{3}} d x

\int \frac{ln ( x ^{18} )}{x} d x

\int (2 x^{3} - 4 x + 3 x) d x

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