| **steepestpath3d.zip** | 1k | 09-10-22 | | **Steepest Path 3D** Enter a functiom f(x,y,z), and the starting point (x,y,z) and find the direction (an unit vector) of the maximum change in f, also known as the steepest ascent path. Enter with parameters steepas3(f,x,y,z). |

| **surfacearea.zip** | 1k | 09-09-08 | | **Surface Area Calculation** enter a function, starting point, ending point as parameters and calculate the surface area of revolution around x-axis. enter in the format like this: surfarea(x^2,1,10) |

| **taylor3d.zip** | 1k | 03-11-18 | | **Taylor 3d!** taylor3d is a function that finds the mth-by-nth degree taylor polynomial of a 3-d function at a point. Great for Physics and Calculus! |

| **ti89vectc.zip** | 1k | 13-10-01 | | **vectc** Vector Calculus: divergence, gradient, curl, laplacian |

| **tiltedconics.zip** | 1k | 11-03-03 | | **TiltedConics** Finds the tilt angle and equation of a standard conics (hyperbola, parabola, circle, eclipse...) |

| **trigder.zip** | 1k | 00-06-06 | | **Trigder v1.0** This program displays the derivatives of the trig functions |

| **trpintegralcenterofmass.zip** | 1k | 09-12-18 | | **Triple Integral: Center of Mass** enter the density(x,y,z) function, as well as the upper bound of z,y,x to find the center of mass of the solid |

| **u_circle.zip** | 1k | 00-05-09 | | **Unit Circle for Calculus v1.0** Unit Circle for Calculus; Provides conversions of coordinates in pi to Degrees and vice-a-versa. Also includes Trig identities and Trig ID's for Intergation and Differentiation. Very usable. A must have for Calculus or Pre-Cal. By Aaron Ligon. |

| **variation_of_parameters.zip** | 1k | 07-12-06 | | **Variation of Parameters** In second order differential equations, we run into differential equations of the type y''+Py'+Qy=f(x). By solving the homogeneous linear differential equation y''+Py'+Qy=0, we obtain the solution yh=C1*y1+C2*y2. Using y1, y2, and f(x) with the variation of parameters, we can find the particular solution, yp, to the nonhomogeneous differential equation. |

| **variation.zip** | 8k | 02-06-19 | | **Variation 2.3.1.6** Etude de variation d'une fonction |

| **zeta.zip** | 3k | 09-11-01 | | **Zeta Function** This is the zeta function, for all TI's except the TI-73. |
