-4arctan(x)=pi

Solution

- 4 arctan (x) = π

Solution

x = - 1

Solution steps

- 4 arctan (x) = π

Divide both sides by

- 4

arctan (x) = - \frac{π}{4}

Apply trig inverse properties

x = - 1

Popular Examples

sin^2(x)=sin(x)cos(x)

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

sin(x)=-(sqrt(3))/2 ,0<= x<= 2pi

sin (x) = - \frac{3}{2}, 0 \leq x \leq 2 π

sin^2(x)=1+cos^2(x)

sin^{2} (x) = 1 + cos^{2} (x)

cos^{2} (θ) = 0

cos(7x)cos(2x)+sin(7x)sin(2x)= 1/2

cos (7 x) cos (2 x) + sin (7 x) sin (2 x) = \frac{1}{2}
