First BC needs to be found. That is done by dividing AB by cosin ABC. Then CD is found by subtracting form BD. After that the angle ACB is 90-ABC (because ABC is right triangle). Then because AE and BD in...
first we expand the equation:(53a +56b) + (37b+3a)now we multiply15a+30b +21b+3anow simplify18a+51b
3x+2y=12 (1) /// 5x+3y=19 (2) /// . (1) x 3---(2) x -2 /// 9x+6y=36///-10x-6y=-38///x+0=-2/// x=2///y=5(2)+3y=19///y=9/3 = 3-///////--> x=2y=3first, we need to make one of the two terms (x or y) of the...
to first think about solving this equation you need to add 1 to both sides producing the equation x^2-2x+1=0 you then need to factorise this equation as it is a quadratic equation (x-1)(x-1) =0 for this t...
To integrate this simple equation add one to the power then divide by the new power for example. 2x^2 becomes 2/3x^3 4x becomes 2x^2 and 1 becomes x plus constant c so the overall integrated equation is 2...
