Q91.
A student has to find the solution of an equation cos(x)=1/2. She has to write the program such that exact values are shown at output. Which of the following codes would help her?
Discuss
Answer: (c).vpa(solve(‘cos(x)=1/2’))
Q92.
Find the error in the following code?
Predicted output: (b + (b² - 4*a*c)(½))/(2*a)
     (b - (b² - 4*a*c)(½))/(2*a)
Code: solve (b*x² + c*x + a == 0)
Present output: -(c + (c² - 4*a*b)(½))/(2*b)
   -(c - (c² - 4*a*b)(½))/(2*b)
Discuss
Answer: (d).solve(a*x² – b*x + c == 0)
Discuss
Answer: (a).syms y(t) a;equn = diff(y,t)==b*y;cnd=y(0)==5;ySol(t)=dsolve(equn,cnd)
Discuss
Answer: (d).The equation has to be solve separately
Discuss
Answer: (c).The equation may be solvable but the function ‘solve’ cannot produce a solution
