1. Create an algebraic expression for sin(arccosx-arcsin3x)2. The cosx=4/5, x lies in quadrant 4. Find sin x/23.Determine all solutions in (0,2pie) for sin4xsin^2x=3,cot^2v(3-1)cotx=v(3), cos^2x=cosx, andtan^2x-6tanx+4=04. Solve; sin(∏/2-x)=1/sec5. Solve; cot+4x+2cot^2x+1=csc4x6. Solve; tan(x+∏/x=(√(3)+3tanx)/(3-√(3)tanx

i have some problems doing trig the first one is: Show that cos(x/2) sin(3x/2) = ½(sinx + sin2x) i know that you are supposed to substitute all those trig function things in it but i kind of forgot how to the only that i can see substituting in is the double angle one for sin2x could anyone walk me through the process maybe?What a very nasty trig identity. I am sure this is not the most efficient way, but the...
