Cos x =sin x [0,2pi) find all solutions in the interval .

1 answer:

7 0

There are several good and valid ways in which to solve this equation. One would be to divide both sides of the equation by cos x, which results in the new equation tan x = 1. Solutions in [0,2pi) of this include pi/4 (45 degrees). Can you find other solutions in [0,2pi)?

What is the solution of the system of linear equations below?

Kipish [7]

Answer:

A is the correct answer

Step-by-step explanation:

To get the fastest answer for these kind of questions, you just have to apply (0, -2) into either one of the 2 equations:

2 * 0 - 6 * (-2) = 12

0 - (-12) =12

0 + 12 = 12 (TRUE)

So the solution will be (0, -2)
