TRIG.SEQ.T Tangent Equations

You can use this next dynamic example to solve trigonometric equations like those in either TRIG.SEQ.SC or TRIG.SEQ.T visually with a mapping diagram of $f$ and the lines in the graph of $f$.

Example TRIG.DSEQ.0 Dynamic Views for solving a trigonometric equation $f(x) = A\ trig (Bx+C) + k = D$ with $A, B \ne 0$ and $trig = \sin, \cos$ or $tan$ on Graphs and Mapping Diagrams.
