9514 1404 393

Answer:

  a) 24×10^-7

Step-by-step explanation:

The number is ...

  0.0000024 = 2.4×0.000001 = 24×0.0000001

The first of these equivalents can be written as ...

  2.4×10^-6 . . . . matches no answer choice (correct answer)

The second of these can be written as ...

  24×10^-7 . . . . matches choice (a)

__

Usually "scientific notation" requires there be one digit left of the decimal point in the mantissa. As we have noted above, no offered answer choice matches this form. The only choice that is equivalent to the given number is the one shown above.

Explanation:

Factorizing your equation we get

cot

(

x

)

=

0

so

cos

(

x

)

=

0

we get the following Solutions in the given interval

x

=

π

72

or

x

=

for the second case we get

cot

(

x

)

=

−

1

so

cos

(

x

)

=

−

sin

(

x

)

and we get

x

=

or

x

=
