3cos(x)=sqrt(3)sin(x)

3 cos (x) = 3 sin (x)

x = \frac{π}{3} + πn

Degrees

x = 6 0^{\circ} + 18 0^{\circ} n

Solution steps

3 cos (x) = 3 sin (x)

Rewrite using trig identities

3 cos (x) = 3 sin (x)

Divide both sides by

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

\frac{3 cos ( x )}{cos ( x )} = \frac{3 sin ( x )}{cos ( x )}

Simplify

3 = \frac{3 sin ( x )}{cos ( x )}

Use the basic trigonometric identity:

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

3 = 3 tan (x)

Switch sides

3 tan (x) = 3

3 tan (x) = 3

Divide both sides by

3

3 tan (x) = 3

Divide both sides by

3

\frac{3 tan ( x )}{3} = \frac{3}{3}

Simplify

\frac{3 tan ( x )}{3} = \frac{3}{3}

Simplify

\frac{3 tan ( x )}{3} : tan (x)

\frac{3 tan ( x )}{3}

Cancel the common factor:

3

= tan (x)

Simplify

\frac{3}{3} : 3

\frac{3}{3}

Apply radical rule:

3 = 3^{\frac{1}{2}}

= \frac{3}{3 ^{\frac{1}{2}}}

Apply exponent rule:

\frac{x ^{a}}{x ^{b}} = x^{a - b}

\frac{3 ^{1}}{3 ^{\frac{1}{2}}} = 3^{1 - \frac{1}{2}}

= 3^{1 - \frac{1}{2}}

Subtract the numbers:

1 - \frac{1}{2} = \frac{1}{2}

= 3^{\frac{1}{2}}

Apply radical rule:

3^{\frac{1}{2}} = 3

= 3

tan (x) = 3

tan (x) = 3

tan (x) = 3

x = \frac{π}{3} + πn

x = \frac{π}{3} + πn

θ, 2 cos (θ) - 3 = 0

3 cos (4 θ - 2 6^{\circ}) + 5 = 7, - 3 0^{\circ} \leq θ < 4 5^{\circ}

tan^{2} (θ) - tan (θ) = 6, 0^{\circ} \leq θ < 18 0^{\circ}

sin (x) = \frac{2 3}{3}

\frac{sin ( 2 x )}{cos ( x )} = 0
