# How do you sketch #y=3 - sin(x)#?

##### 1 Answer

#### 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.
