Sine Function
y=f(x)= Sin(x)
Domain : It is defined for all real values of x
Range : -1 ≤ y ≤ 1
Period:2π
It is a odd function
Graph of sin(x) function
More Graphs on sine function
for y=f(x)=2 sin (x) and y=f(x)=3 sin (x)
We can see that range get increased in the similar way
for y=f(x)=sin (2x)
We can see that range remains but graph get shrink
Cosine Function
y=f(x)= cos(x)
Domain : It is defined for all real values of x
Range : -1 ≤ y ≤ 1
Period:2π
It is even function
Graph of cos(x) function
More Graphs on contains function
for y=f(x)=2 cos (x) and y=f(x)=3 cos (x)
We can see that range get increased in the similar way
for y=f(x)=cos (2x)
We can see that range remains but graph get shrink
Tangent Function
y=f(x)=tan(x)
Domain : It is defined for all real values of x except x ≠(2n + 1)(π/2) where n is any
Range : All the real numbers
Period:π
It is a odd function
