Learning trigonometry? Trig graphs are easy once you get the hang of them. Once you learn the basic shapes, you shouldn't have much difficulty. The main problems A-Level students have, in my experience, are remembering which is y = sin x and which is y =
Trigonometric Functions: sin(x), cos(x), tan(x), cot(x), sec(x), csc(x), asin(x), acos(x), atan(x), acot(x), asec(x), acsc(x) Hyperbolic Trigonometric Functions: sinh(x), cosh(x), tanh(x), coth(x), sech(x), csch(x), asinh(x), acosh(x), atanh(x), acoth(x...
Let's start with the basic sine function,f (t) = sin(t). This function has an amplitude of1because the graph goes one unit up and one unit down from the midline of the graph. This function has a period of2πbecause the sine wave repeats every2πunits. ...
Cosine is the relationship between the leg adjacent to the central angle θ and the hypotenuse of the angle. Central angle and its parts sinθ=yr cosθ=xr. These ratios create various key points as the angle rotates around the circle. The common special relationships can be seen on the uni...
sin(value) cos(value) tan(value) You can use the inverse trig functions (arcsine, y [SINL1]; arccosine, y [COSL1]; and arctangent, y [TANL1]) with real numbers, expressions, and lists. The current angle mode setting affects interpretation. sinL1(value) cosL1(value) tanL1(value) ...
$$\sec x = \displaystyle \frac{1}{\cos x}, \csc x = \displaystyle \frac{1}{\sin x} ~ \textrm{and} ~ \cot x = \displaystyle \frac{1}{\tan x} = \displaystyle \frac{\cos x}{\sin x} $$ Sine and cosine functions are defined for every real number. However, because the ot...
Graphing CalculatorsIn rare cases, the use of advanced mathematical calculators can give incorrect results. One such error occurs with graphing calculators because the screen is not continuous, but a rectangular array of pixels. On some frequently used calculators, the graph of sin 80x looks like ...
The EE button on some graphing calculators is thrown on as a second function which makes it a pain when you are entering these massive numbers. The one major disadvantage of this TI-89 is you must use the 2nd function key to find SIN, COS, and TAN. ...
