Find the value of
Explanation:
Examples:
Solve:
#3x-pi/4 = 0# So
#x= pi/12# is the shift.
Solve:
#4x + pi/2 = 0# So
#x= -pi/8# is the shift.
Solve:
#pix + (3pi)/4 = 0# So
#x= -3/4# is the shift.
Some textbooks use:
Other textbooks use:
For me (having taught out of both kinds of textbook), it's easier just to solve the equation.
