Finding All the Solutions of Trigonometric Equations
The mathematical solution explains how to solve the equation: sin(x+150) = 1/sqrt2 for x between 0⁰ and 360⁰. To begin with, the principle values for (x+150) are found. The fact that a sine curve is periodic is used to find the solution set for (x+150) based upon these two initial values. Subtracting 150 from each...
Solving a Quadratic Equation in Sin(x)
The mathematical solution explains how to solve the equation: 6 cos2x +7sinx = 8 for x between 0 and 4π radians. The equation is rearranged to make the equation 6 cos2x +7sinx - 8 = 0 then the identity sin2 x + cos...
Sketching a Quadratic Function by Firstly Expressing It in Completed Square Form
The mathematical solution explains how to sketch the function f(x) = x[sup]2[/sup] + 6x + 8 by firstly expressing the function in completed square form. A detailed explanation of how to find the completed square form is given. The graph of y = x[sup]2[/sup] is then drawn followed by a series of transformations...
Finding the Minimum Value and Sketching a Quadratic Function
The mathematical solution explains how to find the minimum value and sketch the curve of y = 4x2 + 12x + 10. The first method uses calculus, differentiating the function and equating the differential to zero. The resulting equation is solved to find the x value of the minimum point. This value is then...
