• I'll try to make it as simple as I can 2 x 40 =80 Find 2 numbers which when you multiply gives you 80 and when you add (or subtract) gives you -21 the 2 numbers are : -16 and -5 because (-16x-5)=80 and (-16-5) =-21 **There is an error in yo…

• cosecx(1+cosecx) + cosecx/(1-cosecx) ≡ -2sinx/cos² x Left hand side = cosecx/(1+cosecx) + cosecx/(1-cosecx) => (1/sinx) /( 1 + (1/sinx) )+ (1/sinx)/ ( 1-(1/sinx) ) =>(1/sinx) / ( (sinx+1) /sinx ) + (1/sinx) / ( (sinx-1) /sinx) …

• cosecx(1+cosecx) + cosecx/(1-cosecx) ≡ -2sinx/cos² x Left hand side = cosecx/(1+cosecx) + cosecx/(1-cosecx) => (1/sinx) /( 1 + (1/sinx) )+ (1/sinx)/ ( 1-(1/sinx) ) =>(1/sinx) / ( (sinx+1) /sinx ) + (1/sinx) / ( (sinx-1) /sinx) …
