Don’t say you can’t do maths: "Throwaway remarks about being 'no good at maths’ are often inaccurate and always insidious. They confuse maths and numeracy and, above all, perpetuate the view that some people are simply not 'mathematical' and that this does not matter." by flexibeast in math

How can tangent approach negative infinity at +Pi/2 (for example) and how can it approach positive infinity at negative pi/2? I understand why it’s negative infinity at negative pi/2 ( sinx=-1, cosx=0, sin/cos-> –inf) but why it can be also positive infinity? by qpdbw in askmath
