How do you sketch #y=3 - sin(x)#?
1 Answer
graph{3-sinx [152.03, 188.41, -5.06, 13.14]}
You take test values of x and plot y accordingly. graph{3-sin(x) [97.46, 243, -32.36, 40.44]}
Explanation:
Most preferable values for x would be:-
0
45
60
90
120
135
180
270
360
So remember that
sin0=0
sin45=1/√2
sin60=√3/2
sin90=1
sin120=√3/4
sin135=1/√2
sin180=0
sin270=-1
sin360=0
So from 3, subtract these values and create a sketch. Plot the x-axis with just
In sketches only the shape of the graph and your workings matter, so compare the shape with the graph I've attached with this answer.
