Math Problem Statement

Find the exact value of tan(sin⁻¹(√3/2)).

Solution

The expression in the image is:

tan(sin1(32))\tan\left(\sin^{-1}\left(\frac{\sqrt{3}}{2}\right)\right)

Step 1: Solve sin1(32)\sin^{-1}\left(\frac{\sqrt{3}}{2}\right)

sin1(32)\sin^{-1}\left(\frac{\sqrt{3}}{2}\right) means we are looking for the angle θ\theta such that:

sin(θ)=32\sin(\theta) = \frac{\sqrt{3}}{2}

From trigonometric values, we know that sin(π3)=32\sin(\frac{\pi}{3}) = \frac{\sqrt{3}}{2}. Therefore,

θ=π3\theta = \frac{\pi}{3}

Step 2: Apply the tan\tan function

Now we need to find:

tan(π3)\tan\left(\frac{\pi}{3}\right)

From standard trigonometric values, we know that:

tan(π3)=3\tan\left(\frac{\pi}{3}\right) = \sqrt{3}

Final Answer:

The exact value of the given expression is:

3\sqrt{3}
