So firstly, we need to write the statement "b is two thirds of c" as an equation. This can be written as b=2/3 c. As a ratio this can be written as b:c is 2/3:1 . Now we went to write the equat...
To differentiate we must use implicit differentiation. So: siny=x .Differentiating both sides we get (dy/dx)cosy=1, so (dy/dx)=1/cosy . Using the common identity (sin2(y)+cos2(y)=1) ...

Remember that the equation of a straight line function is: ax+c. a= change of y/ change of xThe steps to follow are:1- find the gradient of the slope2- replace the equation by values coming from any...
All interior angles in a quadrilateral add up to 360 degrees. Adding up what we know so far 60 + 75 + 105 = 240. So the fourth angle must be 360 - 240 which equals 120 degrees.
