Simplify sin(tan^(-1)x)

1 answer:

4 0

Sin (tan^(-1)X)
Sin (1/tan X)
Sin (1/1 / tan X/1)
Tan X = sin X/cos X

Sin (1/1 / sin X/cos X)
Sin (1/1 • cos X/Sin X)
Sin (cos X/sin X )
Cos X.

I believe the correct answer is cos X.

225 students appeared at an examination. Among them, the ratio of the number of students who passed in the first and in the seco

USPshnik [31]

(i) the number of students who passed in the first and in the second division

76+95=171 students

(ii) The ratio of the number of students who passed in the first second and in the third division.

RATIO is 4:5:(25/19) or 4:5: 1.3157894…….

225-29=196 (29students failed)

196-25=171. (Subtract 25 students from the 3rd division)

4x+5x= 171 (171 students from 1st and second division)

9x=171

X=19

4x19=76 5x19= 95 1.31578.....x19= 25

If 1/10m = 1/11m + 1/1100, what is the value of m?

valentinak56 [21]

$\frac{1}{10m} = \frac{1}{11m} + \frac{1}{1100} 
$
$\frac{1}{10m} = \frac{1*1100 + 1*11m}{11m*1100}$
$\frac{1}{10m} = \frac{1100 + 11m}{12100m}$
$1*12100m = 10m(1100 + 11m)$
$12100m = 11000m + 110 m^{2}$
$12100m-11000m = 110 m^{2}$
$1100m = 110 m^{2}$
m=10
