The inverse of the function To get the original amount back, or simply calculate the other currency, one must use the inverse function. Although the units in this instructional framework emphasize key standards and big ideas at Inverse trigonometric functions are also called “Arc Functions” since, for a given value of trigonometric functions, they produce the length of arc needed to obtain that particular value. Initially, their development dealt with transformation of geometric objects and solution of systems of linear equations. ɖ�i��Ci���I$AҮݢ��HJ��&����|�;��w�Aoޞ��T-gs/� APPLICATION OF DERIVATIVES IN REAL LIFE The derivative is the exact rate at which one quantity changes with respect to another.
