arcsin((900x^2-1)/(900x^2+1))=1.18

الحلّ

arcsin (\frac{900 x ^{2} - 1}{900 x ^{2} + 1}) = 1.18

الحلّ

x = \frac{1 + sin ( \frac{59}{50} )}{30 1 - sin ( \frac{59}{50} )}, x = - \frac{1 + sin ( \frac{59}{50} )}{30 1 - sin ( \frac{59}{50} )}

خطوات الحلّ

arcsin (\frac{900 x ^{2} - 1}{900 x ^{2} + 1}) = 1.18

Apply trig inverse properties

arcsin (\frac{900 x ^{2} - 1}{900 x ^{2} + 1}) = 1.18

arcsin (x) = a \Rightarrow x = sin (a)

\frac{900 x ^{2} - 1}{900 x ^{2} + 1} = sin (1.18)

sin (1.18) = sin (\frac{59}{50})

sin (1.18)

\frac{900 x ^{2} - 1}{900 x ^{2} + 1} = sin (\frac{59}{50})

\frac{900 x ^{2} - 1}{900 x ^{2} + 1} = sin (\frac{59}{50})

\frac{900 x ^{2} - 1}{900 x ^{2} + 1} = sin (\frac{59}{50})

حلّ:

x = \frac{1 + sin ( \frac{59}{50} )}{30 1 - sin ( \frac{59}{50} )}, x = - \frac{1 + sin ( \frac{59}{50} )}{30 1 - sin ( \frac{59}{50} )}
