Q) Write python keywords from the following list of words : And Class PASS if exec
PRINT Not.
ans) class, if
Q) write python statements for the following equations :
(a) rootl= -b+√( b^2-4ac)/2a
=> root1 = (-b+math.sqrt (b**2-4*a*c))/2*a
(b) result = ((2xy-9y)/2xy^3)-((4yx^2)/2y) => result = ((2*x*y-9*y)/2*x*y**3)-( (4*y*x**2)/2*y)
(c) result = 2cos1/2 (x+y) cos1/2 (x-y) +e^x-1-x/4+tan (x) -log (v)
=> result = 2*math.cos (0.5 (x+y)) *math.cos(0.5 (x y)) +math.exp (x)-1-x/4+math.tan (x)
-math.log (v)
Q) how does the effect of the following two statements differ :
(a)x+=x+10
=> it is equivalent to x=x+x+10. for example: if x=2, output will be x=14.
(b)x=x+10
=> it is equivalent to x=x+10. for example: if x=2, output will be x=12.
