Tan theta x sin phi
WebThe differentiation of trigonometric functions is the mathematical process of finding the derivative of a trigonometric function, or its rate of change with respect to a variable.For example, the derivative of the sine function is written sin′(a) = cos(a), meaning that the rate of change of sin(x) at a particular angle x = a is given by the cosine of that angle. These are also known as the angle addition and subtraction theorems (or formulae). The angle difference identities for and can be derived from the angle sum versions by substituting for and using the facts that and . They can also be derived by using a slightly modified version of the figure for the angle sum identities, b…

WebMar 12, 2024 · This paper proposes an analytical approach for assessing rock slope stability based on a three-dimensional (3D) Hoek–Brown (HB) criterion to consider the effects of intermediate principal stress. The 3D HB criterion, considering an associate flow rule, is utilized to describe the perfectly plastic behavior of rock mass under a plane strain … WebThe basic relationship between the sine and cosine is given by the Pythagorean identity: where means and means This can be viewed as a version of the Pythagorean theorem, and follows from the equation for the unit circle. This equation can be solved for either the sine or the cosine: where the sign depends on the quadrant of
