3m=sin(-8)/(5)

Solve the equation and check your result.3m=5m-(8)/(5)

Solve "sin"^(-1)(3/(5))+"sin"^(-1)(8/(17)) .

Value of the expression 2[sin^(8)[(pi)/(16)]+sin^(8)[(3 pi)/(16)]+sin^(8)[(5 pi)/(16)] + sin^(8)[(7 pi)/(16)]]

Show that : sin^(-1)(8/(17))+sin^(-1)(3/5)=sin^(-1)(77/85)

Prove that : sin^(-1)(8/17)+sin^(-1)(3/5)=sin^(-1)(77/85) .

"sin"^(2)pi/8" + sin"^(2)(3pi)/8" + sin"^(2)(5pi)/8" + sin"^(2)(7pi)/8=

"sin"^(4)pi/8" +sin"^(4)(3pi)/8" +sin"^(4)(5pi)/8" +sin"^(4)(7pi)/8=

The velocities of light in two different media are 2* 10^8 m/s and 2.5 * 10^8 m/s respectively.The critical angle for these media is sin^(-1)((1)/(5)) sin^(-1)((4)/(5))
