I would like an app for geometry. What I want to include:

Area of all regular shapes

Volume of all regular objects, as well as irregular objects. (Simply base area*height for irreg)

Surface area of all regular objects, including irregular pyramids

Program where you input two points and it gives: slope, distance, midpoint, y-intercept, x intercept, slope-intercept form, general(regular)form, and point-slope form

The quadratic formula

Triangle solver (like ZATTRI)

A diagram of the unit circle that shows the main points and angles, able to be zoomed in, allow for input of tracing to a certain angle or point

Sin, cos, tan, sec, csc, and cot converter

I would also like an app to convert:

Degrees to radians and back

All forms of pressure

Lengths

Masses

Volumes

Metric prefixes

live the life because the life is good —vivir la vida, porque la vida es buena

Vie la vie que la vie est bonne quod est bonum vitae in vita

lebe das Leben, weil das Leben ist gut —vivere la vita, perché la vita è buona
