o, I am again going to discuss using the SIN function for calculating height with two known variables. The length of a shadow cast from a building and the calculated angle from the top of the building to the end of the shadow. In this case Length = 70m and
= 75 deg.
In Mathcad I can set up my variables so that they can be changed to whatever values I need and an equation that will automatically calculate the answer any time I change the variables. In this case, I used SIN (radians)(length) to calculate the missing dimension and deg(pi/180) to convert degrees to radians.
and as shown below, by simply changing the variable inputs it automatically recalculates the answer.
