Math Problem Statement

Tan(x)+3^.5=0

Solution

To solve the equation:

tan(x)+3=0\tan(x) + \sqrt{3} = 0

we can isolate tan(x)\tan(x):

tan(x)=3\tan(x) = -\sqrt{3}

Now, we need to find the values of xx such that tan(x)=3\tan(x) = -\sqrt{3}.

  1. Identify the reference angle: tan(x)=3\tan(x) = \sqrt{3} at x=π3x = \frac{\pi}{3} (or 6060^\circ) in radians.

  2. Find the angles where tan(x)=3\tan(x) = -\sqrt{3}: The tangent function is negative in the second and fourth quadrants. Thus, the solutions are:

    x=ππ3=2π3x = \pi - \frac{\pi}{3} = \frac{2\pi}{3} and x=2ππ3=5π3x = 2\pi - \frac{\pi}{3} = \frac{5\pi}{3}

  3. Include the periodicity of tangent: Since tan(x)\tan(x) has a period of π\pi, the general solutions are:

    x=2π3+nπx = \frac{2\pi}{3} + n\pi and x=5π3+nπx = \frac{5\pi}{3} + n\pi

where nn is any integer.

Therefore, the solutions to the equation are:

x=2π3+nπandx=5π3+nπx = \frac{2\pi}{3} + n\pi \quad \text{and} \quad x = \frac{5\pi}{3} + n\pi

for any integer nn.

  3. How does the sign of tangent affect the quadrant where the solution lies?
  4. How would the solution differ if the equation was tan(x)3=0\tan(x) - \sqrt{3} = 0?
  5. What are the solutions to other trigonometric equations, like sin(x)=12\sin(x) = -\frac{1}{2}?

Tip: Always check which quadrants a trigonometric function's value is positive or negative to identify potential solutions accurately.
