Question

Graphing of the sine and cosine functions

Answer 1

\[y=2\sin (\frac{ \pi }{ 2 }x)\]

I use the table to solve it but my question is when do you use radians for the start or degrees.

Answer 2

Answer 3

Generally use radians for these.

Answer 4

My teacher uses a graph and i am using it and when i put like lets say'

y=2cos(1/2x)
I have the graph

0
pi / 2

When you plug in (pi/2) into the equation it suppose to give you the 'Y' but i get a decimal and the cos of (PI/4) is (squareroot 2/2) times 2 is just squareroot2

Answer 5

How about you graph that

Answer 6

What's wrong with a decimal? You can graph a decimal...

Answer 7

Wait nvm

Answer 8

I was thinking something different
