Below are four problems based on proportionality, you have to form equations to find unknown variables and constants.
Points to remember :
1) We say that x is directly proportional to y, if x = ky for some constant k
2) We say that x is inversely proportional to y, if xy = k for some constant k
Below are three problems based on differential equations. Before solving the problem, you have to remember the differential formulas.
If dy = [(secx - y) / tanx)]dx, then the curve is:
a) y = x(sinx) b) y = x(cosx) c) y = x(secx) d) y = x(cosecx)
Answer : d) y = x(cosecx)
Below are three problems on series. You have to find the sum of the given series upto nth term.
Formulas to remember :
1) (1+y)(-n) = 1 - ny + n(n+1)/2! y2 - n(n+1)(n+2)/3! y3 + ...
2) (1-y)(-n) = 1 + ny + n(n+1)/2! y2 + n(n+1)(n+2)/3! y3 + ...
