\frac{3a}{b}\cdot \frac{b^2}{12c}=\frac{3ab^2}{12cb}

Notice we can simplify by cancelling a b and reducing 3/12:

=\frac{ab}{4c}

This cannot be simplified further.

A=2

Period:

It is time completed after which value repeats itself

so, we get

T=\pi -0

T=\pi

so,

Lunna [17]

f(x)=lnx

y=f(x)

dy/dx= 1/x

tangent at (x,y) has slope 1/x

eqn of tangent is y = mx + c

since the tangent passes through origin, c=0

substitute y = lnx and m= 1/x to above eqn

lnx = 1

x=e

y=lne=1
