2x + 4 = 2 2x = -2 x = -1
What is 2x-2 equals 10?
2x-2 = 10 2x= 10+2 2x=12 x= 12/2 x=6
How would you solve the integral of 1 plus tan2x plus tan squared 2x?
Integral of 1 is x Integral of tan(2x) = Integral of [sin(2x)/cos(2x)] =-ln (cos(2x)) /2 Integral of tan^2 (2x) = Integral of sec^2(2x)-1 = tan(2x)/2 - x Combining all, Integral of 1 plus tan(2x) plus tan squared 2x is x-ln(cos(2x))/2 +tan(2x)/2 - x + C = -ln (cos(2x))/2 + tan(2x)/2 + C
What is the answer to -2x - 2 4?
- 2X - 2 = 4 ?If so.....,- 2X - 2 = 4add 2 to each side- 2X = 6divide each sides integers by - 2X = - 3==========check- 2(- 3) - 2 = 46 - 2 = 44 = 4-------------checks
