Tan ^-1 (-1). enter your answer in radians
Assoli18 [71]

Answer:

\theta=\frac{3\pi}{4},\theta=\frac{7\pi}{4}

Step-by-step explanation:

we are given

tan^{-1}(-1)

Let's assume angle as theta

\theta =tan^{-1}(-1)

so, we get

tan(\theta)=-1

now, we can use unit circle and find theta

and we get

\theta=\frac{3\pi}{4},\theta=\frac{7\pi}{4}

So, solution is

\theta=\frac{3\pi}{4},\theta=\frac{7\pi}{4}

What is the length of the diagonal of a cube of 4 inches
BartSMP [9]

First find the length of the diagonal of a square of side 4 inches:


d^2 = 4^2 + 4^2 = 2*4^2 = 32. Then the diagonal of the cube has length


sqrt( 32 + 4^2) = sqrt(32+16) = sqrt(48) = 4sqrt(3).
