Can anyone help me with these equations.

1.

make T the subject of the logarithmic relationship

M= V In T

2.

the following formula occurs in thermodynamics

Q= R0 In (V2/V1)

Transform to make V2 the subject.

3.

The ratio of belt tensions in a v-belt transmission is given by

R=γ0 / e^sinα

transform to makeα the subject
