LO4: Examine how differential and integral calculus can be used to solve engineering problems. a- If two resistors with resistances R1 and R2 are connected in parallel as shown in the figure below, their electrical behaviour is equivalent to a resistor of resistance R such that = + . If R1 changes with time at a rate r = and R2 is constant, express the rate of change of the resistance of R in terms of R1 and R2. b- If an object with a speed v giving by the equation v ( t ) = 1 + 4t + 3 where t is the time taken to move per minute, what is the travelled distance during the third minute?
