slope space of space the space tangent space at space straight x equals straight pi over 4 space is space 2 equals straight m.
straight x equals straight pi over 4 rightwards double arrow straight y equals 1
Equation space of space tangent space passing space through space open parentheses straight pi over 4 comma 1 close parentheses space and space slope equals 2
straight y minus 1 equals 2 open parentheses straight x minus straight pi over 4 close parentheses
rightwards double arrow straight y equals 2 straight x plus 1 minus straight pi over 2
Find space the space required space area space using space definite space integration space on space function space and
equation space of space straight a space line space from space 0 space to space straight pi over 4.

space end style
