First use the sine rule (that a/sin(A)=b/sin(B)=c/sin(C)) to find the value of B. a/sin(A)=b/sin(B) so B=arcsin(bsin(A)/a) which is approximately equal to 28.82. Since the angles of a triangle have 18...
sin-1(√2 / 4 ) = 20.7•Looking at a sin graph this is also true at 180-20.7 = 159.3•x = 159.3•
y = 4x^3 - 6x^2 + 7 dy/dx = 12x^2 -12x
Straight line equations always come in the form y=mx+c, where m is the gradient of the line (how steep it it) and c is the point where the line crosses the y axis (the y intercept).If you are given two po...
x2+7x+10 = 0 factorise this into the form (x+a)(x+b)=0 by finding out what 2 numbers multiply to make 10 and add up to 7. the 2 numbers that fit this criteria are 5 and 2 so (x+5)(x+2)=0, if we...
