4tan^2(x)+7tan(x)-4=0,cot(2x)

4 tan^{2} (x) + 7 tan (x) - 4 = 0, cot (2 x)

No Solution for x \in R

Solution steps

4 tan^{2} (x) + 7 tan (x) - 4 = 0, cot (2 x)

Solve by substitution

tan (x) = \frac{- 7 + 113}{8}, tan (x) = \frac{- 7 - 113}{8}

tan (x) = \frac{- 7 + 113}{8}, cot (2 x) :

No Solution

tan (x) = \frac{- 7 - 113}{8}, cot (2 x) :

No Solution

tan^{3} (x) = tan^{2} (x), 0 \leq x \leq 2 π

11.75 = 5 sin (\frac{π t}{6} - \frac{7 π}{6}) + 8

0 = - 2 sin (x) - 2 cos (2 x)

- sin (c) + cos (c) + 1 = 0

cot (a) = \frac{7}{51}
