Answer
Divide 32 into 4 parts which are in AP such that the product of extremes is to the product of means is 7: 15.
Using integration find the area of triangle from by the positive x axis and tangent and normal yo the circle x2 y2=4 at (1,√3)
It can be easily solved .make ∆RMP~∆PMQ
∆PMQ~RMP
∆PMQ~RMP
- =PM/RM=MQ/MP=PQ/RM
- CROSS MULTIPLY PM/RM AND MQ/MP
- We get PM*PM=QM*MR
- So (PM)^2 =QM *MR
From the differential equation of the family of circles having center on y_ axis and radius 3 units.
