tan^2(x)-6tan(x)-7=0

tan^{2} (x) - 6 tan (x) - 7 = 0

x = 1.42889 \dots + πn, x = \frac{3 π}{4} + πn

Solution steps

tan^{2} (x) - 6 tan (x) - 7 = 0

Solve by substitution

tan (x) = 7, tan (x) = - 1

tan (x) = 7 : x = arctan (7) + πn

tan (x) = - 1 : x = \frac{3 π}{4} + πn

Combine all the solutions

x = arctan (7) + πn, x = \frac{3 π}{4} + πn

Show solutions in decimal form

x = 1.42889 \dots + πn, x = \frac{3 π}{4} + πn

3 sin (2 x) = 2, 0 \leq x \leq π

cos (θ) = \frac{2}{2.24}

cot (α) = \frac{2}{3}

- 900 cos (30 x) = 0

sin^{2} (x) = \frac{( 9 m - 9 )}{7}
