write on paper please.

Concept:
Any function will be odd function if,
Function will be even function if,
For the trigonometric function:
Function will be odd function if
Function will be even function if
Solution:1
We know sin is and odd function so
Solution 2:
We know that sec is an even function, so
Solution 3:
We know that tan is an odd function
So,

Solution 4:
We know that cos is an even function
Solution: 5
We know that cosec is an odd function, so

Solution 6:
Given,
We know that
Now, substituting the value of
Solution 7:
Given,
is in the III quadrant.
From the above, we can say that, in the III quadrant the values of the trigonometric functions are given below-
Solution 8:
The sketch of the graph is given below-
The domain of the function
Range of the function =
Period =
It is vertically asymptotes
x-intercept =
y-intercept =
Hence, it is odd function.
Solution 9:
The given function is
We know that the general equation of sine function
Now, comparing general equation of sine function with the given function,
Hence, amplitude of the function...
