Question

If X=0,then the value of cos X+x^3/125

Answer 1

Answer:

given that x=0

cos x+x^3/125

=cos 0+0^3/125

=cos 0

=1

Answer 2

SOLUTION

TO DETERMINE

If x = 0 then the value of

$\displaystyle \sf{ \cos x + \frac{ {x}^{3} }{125} }$

EVALUATION

Here the given expression is

$\displaystyle \sf{ \cos x + \frac{ {x}^{3} }{125} }$

Putting x = 0 we have

The given expression

$\displaystyle \sf{ = \cos 0 + \frac{ {0}^{3} }{125} }$

$\sf = 1 + 0$

$\sf = 1$
