3.6=0.116cos(4.17x)

3.6 = 0.116 cos (4.17 x)

No Solution for x \in R

Solution steps

3.6 = 0.116 cos (4.17 x)

Switch sides

0.116 cos (4.17 x) = 3.6

Multiply both sides by

1000

0.116 cos (4.17 x) = 3.6

To eliminate decimal points, multiply by 10 for every digit after the decimal pointThere are

3

digits to the right of the decimal point, therefore multiply by

1000

0.116 cos (4.17 x) \cdot 1000 = 3.6 \cdot 1000

Refine

116 cos (4.17 x) = 3600

116 cos (4.17 x) = 3600

Divide both sides by

116

116 cos (4.17 x) = 3600

Divide both sides by

116

\frac{116 cos ( 4.17 x )}{116} = \frac{3600}{116}

Simplify

cos (4.17 x) = \frac{900}{29}

cos (4.17 x) = \frac{900}{29}

- 1 \leq cos (x) \leq 1

No Solution for x \in R

cos (x) = \frac{3}{2}, sin (2 x), - 9 0^{\circ} \leq x \leq 0^{\circ}

sin (x) = 2 \cdot 589.594 \cdot 1 0^{- 9} \cdot 300 \cdot 1 0^{3}

sec (x) = - \frac{\frac{1}{2}}{3}

cos^{2} (θ) + \frac{2 0 ^{2} cos ( θ )}{9.81 ( 1 )} - 1 = 0

3 sin (θ) + 5 = 6
