How do you solve an equation where you have to do inverse sine? My math problem is: sinx=10/20. If someone could help me through this, I would be grateful.
+33661 arcsine is the same as asin which is the same as sin-1
Press 2nd then asin on the calculator
$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}^{\!\!\mathtt{-1}}{\left({\frac{{\mathtt{10}}}{{\mathtt{20}}}}\right)} = {\mathtt{30^{\circ}}}$$
.
