Describe the differences in the graphs of the sin, cosine and tangent functions.

To draw the graph of any  trigonometric function we should remember few values

For Sin FUNCTION:

Example: Sin0 =0  , sin 30= 1/2 , sin 90=1

Range  :

Domain :

Period :

Similarly for Cosine

Cos0=1  , cos30=  , cos90=0

Range :

Domain :

Period :

For Tangent

tan 0= 0,  tan 30=  , tan90=

Range :

Domain :

Period :

its 69.420

step-by-step explanation:

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
