integration e^x cosxdx
9sin2(3x).cos(3x)=4sin(3x).cos2(3x)
factorize 8x squared +_5x+ 10
i am thinking of a number 10% of my number is 40 100% is
x+1/x =4
x²
sin(5 π\piπ -x)+cos(-11 π\piπ+x)-sin(3 π\piπ -x)+sin(7 π\piπ +x)
x/0,21-1455,66=x
Solve the given equations to find the value of the variable and verify the answer.
− 1 = 3a + 71
