The cos(pi/2-x) is equivalent to sinx because the cosx graph is just the sinx graph but shifted to the left by a phase difference of pi/2 radians, and cos(pi/2 - x) is also shifting the cosx graph to the ...

The general equation for a circle is as follows:(x-a)^2+(y-b)^2=r^2where (a,b) are the coordinates of the centre of the circle and r is the radius of the circle.x^2+y^2-4x-8y+11=0In this case, group all x...

To differentiate an equation, the first step is multiplying the coefficients of the variables (the coefficient is the number a variable is already being multiplied by, for example in 6x the coefficient of...

First of all I would find 1% by dividing 1546 by 100:1546/100 = 15.46Then I would multiply this by 24 to find 24%:15.46x24 = 371.04 So 24% of 1546 is 371.04
