Find , when
Theorem: y and x are given in a different variable that is t . We can find by finding and and then dividing them to get the required thing.
Let us assume u=
=
=
= {by using divide rule, }
Putting value of u
=
= ………..(1)
Let assume v=
= {by using divide rule, }
Putting value of v
=
=
= ……….(2)
Dividing (1) and (2), we get
=
=
