Musicgal SG yep.. is sin r multiply by sin r equals (sinr)^2 ?but you can't make sin ^2 in the calculatori have a equation sin r * sin r = 0.56and i hv to find r.pls help! thanks!
fudgester SG sin^2 r = 0.56So just square root both sides, and you get sin r = sqrt (0.56).Go and work out for yourself what sqrt (0.56) is with your calculator.
-Wanderer- SG yep.. is sin r multiply by sin r equals (sinr)^2 ?but you can't make sin ^2 in the calculatori have a equation sin r * sin r = 0.56and i hv to find r.pls help! thanks! Yes. sin r * sin r = sin^2 r
