u = -b + 21 u = -2b + 30 Check it out - both equations are ... u " already. Thus, -b + 21 = -2b + 30 -b + 2b = 30 - 21 b = 9. u = -b + 21 = -(9) + 21 = 12 u = -2b + 30 = -2(9) + 30 = 12 So, the ...

firstly you should expand that ( u +3)^3 into ( u +3)( u +3)( u +3) *remember that foil means first, outer...out using foil method ( u +3)( u +3) u ^2 +3u +3u + 9 combine like terms u ^2 +6u + 9 and finally multiply this by the remaining ( u +3) using foil...

sin( u / 2) = sqrt( (1 - cos( u )) / 2) cos( u / 2) = sqrt( (1 + cos( u )) / 2) tan( u / 2) = sin( u /2) / cos( u /2) = sqrt...sqrt( (8/5) / 2) = sqrt( 4/5 ) = 2 / sqrt(5) = 2 * sqrt(5) / 5 sin( u /2) = 2 * sqrt(5) / 5 sqrt( (1 - 3/5) / 2) = sqrt( (2/5) / 2...

∫ u du/(16 + u ^2) Let w = 16 + u ^2 then dw = 2u du so (1/2) dw = u du We now have (1/2) ∫ dw/w = (1/2) ln w = (1/2) ln (16 + u ^2) + C
