Answer:

Step-by-step explanation:
Answer:
The required graph is shown below.
Step-by-step explanation:
Consider the provided equation 
We need to draw the graph of the equation.
Put x=0 in the above equation.


The coordinate is (0,2).
Put y=0 in the given equation.



The coordinate is (
,0).
Now draw the graph by using the above coordinates.
The required graph is shown below.
<span>sin 90° = 1
</span>
cos 0° = 1
There's a simple formula : <em>sin θ = cos (90°- θ)</em> or <em>cos θ = sin (90°- θ) </em>
So : cos 0° = sin (90° - 0°) = sin 90° = 1
