Question

EXPLAIN how to use the unit circle to find theta when cos theta equals negative sin theta, 0 ≤ theta ≤ 2π.
Please answer and ill give you brainiest

Answer 1

Answer:

The Cos Θ is the ratio of the adjacent side to the hypotenuse, where (Θ is one of the acute angles. The cosine formula is as follows: Cos \Theta = \frac{Adjacent}{Hypotenuse}

Step-by-step explanation:

I know that I'm not accurate, so for that my apologies

but this is something I know .. so I really hope this helps

Answer 2

Answer:

$\huge\underbrace\mathfrak\pink{Answer}$

• Once we can find the sine, cosine and tangent of any angle, we can use a table of values to plot the graphs of the functions y = sin x, y = cos x ... Since each angle θ determines a point P on the unit circle, we will define.
