Find y" by implicit differentiation for
Solution:
Consider the given equation above
Since the given equation above is not a function, then we have to differentiate it by implicit differentiation as follows
but
or
then the above equation becomes
Rationalize the denominator in order to eliminate the radical sign at the denominator, we have
Take the derivative with respect to x, we have
Rationalize the denominator in order to eliminate the radical sign at the denominator, we have

Prove that
Solution:
Consider the given equation above
In proving the trigonometric functions, the first thing that you have to do is to choose the more complicated side of the equation and then simplify and compare with the other side of the equation if they are equal or not.
In this case, the left side of the equation is more complicated and we have to simplify it as follows
The numerator is the sum of cubes. We can use the principles of Algebra in factoring the numerator as follows
but
then the above equation becomes
Therefore,

Prove that
Solution:
In proving the trigonometric functions, the first thing that you have to do is to choose the more complicated side of the equation and then simplify and compare with the other side of the equation if they are equal or not.
In this case, let's choose the left side of the equation as follows
If you will continue to expand further the above equation, it will be more complicated and longer. Let's substitute all trigonometric functions with another variables as follows
Let
then the above equation becomes
since
then the above equation becomes
