The angle was calculated from measurements done with a metric tape ([+ o -] 1 mm) of the height of the heap at two points and the horizontal length between them, applying the

trigonometric equation:

From the historical perspective, in this process of development and expansion, for equations, the linear equation, dual linear equation, quadratic equation, multiple equation, geometry equation,

trigonometric equation, ordinary differential equation, partial differential equation, integral equation, and the like are appeared step by step; for solutions, the approximate solution, accurate solution, analytical solution, numerical solution, and the like are also appeared step by step.

Biquadratic

trigonometric equation 2 [tan.sup.4] 3x - 3 [tan.sup.2] 3x + 1 = 0 is too complicated for Maxima and Sage, but 2[t.sup.4] - 3[t.sup.2] + 1 = 0 is solvable.

The first approach is based on a basic

trigonometric equationThe solution for the

trigonometric equation (1) is:

Four areas are discussed more thoroughly - multiplicity of roots, extraneous roots, literal equation and

trigonometric equation.

This model is suitable to implement

trigonometric equations in FPGA devices.

* This method can be used to solve

trigonometric equations.

I'M sure wind power enthusiasts Trefor Davies and Peter Leach (Letters) would never put pen to paper, advising mathematicians on how to carry out complex vector or

trigonometric equations.

Physicists have complex

trigonometric equations, known as the Helmholtz Function and the

Even though mathematics education in Australia varies considerably between various States due to the different education systems in place in each State, the trigonometric functions and subsequently solving

trigonometric equations including the periodicity of those functions are included in the various levels of mathematics learned in Years 11-12.

This two

trigonometric equations system are compatible according to a and [beta] variables.
