Q1:

It is desired to evaluate the expression
F = B cos Y + C cos2 Y + A cos3 Y
 The Pascal equivalent to ensure minimum computer time should be written as

A
F = B * COS (Y) + C * SQR (COS (Y) + A * COS (Y) * COS (Y) * COS (Y)

B
F = B * COS (Y) + C * SQR [COS (Y)] + A * COS (Y) * SQR [COS (Y)]

C
F = B * COS (Y) + C * COS(Y) * COS (Y) + A * COS (Y) * COS (Y) * COS (Y)

D
X = COS(Y)
Z = SQR (X)
F = B * X + C * Z + A * X * Z

ANS:D -

X = COS(Y)
Z = SQR (X)
F = B * X + C * Z + A * X * Z
