3(sin(x)-cos(x))=2(sin(x)+cos(x))

3 (sin (x) - cos (x)) = 2 (sin (x) + cos (x))

x = 1.37340 \dots + πn

Degrees

x = 78.69006 \dots^{\circ} + 18 0^{\circ} n

Solution steps

3 (sin (x) - cos (x)) = 2 (sin (x) + cos (x))

Subtract

2 (sin (x) + cos (x))

from both sides

sin (x) - 5 cos (x) = 0

Rewrite using trig identities

sin (x) - 5 cos (x) = 0

Divide both sides by

cos (x), cos (x) \neq = 0

\frac{sin ( x ) - 5 cos ( x )}{cos ( x )} = \frac{0}{cos ( x )}

Simplify

\frac{sin ( x )}{cos ( x )} - 5 = 0

Use the basic trigonometric identity:

\frac{sin ( x )}{cos ( x )} = tan (x)

tan (x) - 5 = 0

tan (x) - 5 = 0

Move

5

to the right side

tan (x) - 5 = 0

Add

5

to both sides

tan (x) - 5 + 5 = 0 + 5

Simplify

tan (x) = 5

tan (x) = 5

Apply trig inverse properties

tan (x) = 5

General solutions for

tan (x) = 5

tan (x) = a \Rightarrow x = arctan (a) + πn

x = arctan (5) + πn

x = arctan (5) + πn

Show solutions in decimal form

x = 1.37340 \dots + πn

\frac{sin ( 2 x )}{sin ( x )} = 1

θ, ma = t sin (θ) - m g

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

\frac{cot ( a )}{cos ( a )} = cos (a)

cos (x) - 2 = 0
