cos(x)tan(x)=10tan(x)

cos (x) tan (x) = 10 tan (x)

x = πn

Degrees

x = 0^{\circ} + 18 0^{\circ} n

Solution steps

cos (x) tan (x) = 10 tan (x)

Subtract

10 tan (x)

from both sides

cos (x) tan (x) - 10 tan (x) = 0

Factor

cos (x) tan (x) - 10 tan (x) : tan (x) (cos (x) - 10)

cos (x) tan (x) - 10 tan (x)

Factor out common term

tan (x)

= tan (x) (cos (x) - 10)

tan (x) (cos (x) - 10) = 0

Solving each part separately

tan (x) = 0 or cos (x) - 10 = 0

tan (x) = 0 : x = πn

tan (x) = 0

General solutions for

tan (x) = 0

tan (x)

periodicity table with

πn

cycle:

x 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} \frac{π}{2} \frac{2 π}{3} \frac{3 π}{4} \frac{5 π}{6} tan (x) 0 \frac{3}{3} 13 \pm \infty - 3 - 1 - \frac{3}{3}

x = 0 + πn

x = 0 + πn

Solve

x = 0 + πn : x = πn

x = 0 + πn

0 + πn = πn

x = πn

x = πn

cos (x) - 10 = 0 :

No Solution

cos (x) - 10 = 0

Move

10

to the right side

cos (x) - 10 = 0

Add

10

to both sides

cos (x) - 10 + 10 = 0 + 10

Simplify

cos (x) = 10

cos (x) = 10

- 1 \leq cos (x) \leq 1
