    I wish these people would make similar apps for all of math. 50% of the human brain is used to process visual data. Apps that translate math into visuals like this one are the best way to understand complex math.

    Creo que estaría mejor si se pudiese elegir de forma individual en los ajustes el valor que quieres ver. En esta versión seno y coseno van juntos como la tangente y cotangente. Estaría bien poder ver por ejemplo solo el coseno o el seno. .... Pero les felicito, la aplicación está muy bien y es útil para explicar trigonometria a los niños
