The function has a discontinuity at x = 0 because it is not defined at x = 0. ... 1 Based on the graph, why do you think y = tan(x) is said to have an infinite ... The period of the tan(x) tan ( x ) function is π π so values will repeat every π π radians in both directions. x= ... (d) Does the line tangent to the graph of h at x = 4 lie above or below the graph of h for. 4 x ? Why? (a) ( ) 0. h xa at. 2 x o. Local minima at. 2 x and at. 2. If tanx=0.3 , then how do you find tan 2x? https://socratic.org/ ... Since F'(0)=1 (that is, the graph of F is tangent to the diagonal at x=0) this fixed point must be neutral. Moreover, graphical analysis suggest that the fixed ... x + cos. 2 x = 1 sec2 x = 1 + tan. 2 x. We will now use these in the solution ...
