NISA [10]

Answer:

Step-by-step explanation:

W (-6,-2) to W' (-2,6)

X (-2,-2) to X' (-2,2)

Y (-2,-6) to Y' (-6, 2)

Z (-5,-6) to Z' (-6, 5)

I think that those are the answers

What are the values that satisfy the trigonometric equation for: 0≤q≤2π ?<br> sin(∅)+tan(−∅)

Mrac [35]

Answer:

First choice: 0, pi

Step-by-step explanation:

I am assuming the equation is

$\sin q + \tan (-q) = 0$

(the =0 part is missing in the original problem)

$\sin q + \tan (-q) = 0\\\sin q + \frac{\sin (-q) }{\cos (-q)} = 0\\\sin q + \frac{-\sin q}{\cos q}=0\\\sin q = \frac{\sin q}{\cos q}\\\sin q \cdot \cos q = \sin q\,\,,\,\,\, 0\leq q \leq 2\pi\\\implies\\\cos q = 1 \implies q=\{0, 2\pi\}\\\mbox{or}\\\sin q = 0 \implies q=\{0, \pi, 2\pi\}\\\implies\\q=\{0,\pi,2\pi\}$
