Q4. Write a CH program that accepts two vectors and the inclined angle and show the resultant vector using the relation R2 = (a? + b2 + 2 ab cosx), where a, b the vectors and X is the inclined angle in radians and R is the resultant vector. Q5. Write a C++ program that accepts the three resistor values in Kio Ohms and shows the series and parallel equivalent resistance in Kilo Ohms (one program does both calculation). Q6. Write a CH program that accepts three coefficients a, b and c of quadratic equation and display roots and incase if the roots are imaginary just need to display a message that roots are complex (using if...else statement) Please note that I will explain if Statement in the next lecture
