Explain what each of the following expressions means. Evaluate each expression for x = 0.5. Some of these may be asking for inverse and not raising to exponent of -1. Enter the exact value for angles, and round any values to three decimal places. sin^-1 x = ? sin(x^-1) = ? (...
Using VSEPR what is the shape of ammonia (NH3) and water (H2O) when bonded to a hydrogen bond?
Compute the amount of heat released (absolute value) when 1.1 kg of liquid ethanol is burned in excess oxygen to make carbon dioxide and liquid water
verify the identity: (sin^3x-cos^3x)/(sinx-cosx)=1+sinxcosx
verify the identity: (1-cosx)(1+cosx)= sin^2 x
solve: tan x/2= sqrt3/ 3
What shape has perperndular line segments?
