Deriving the formula for angle between two straight lines

In this video , I showed how to obtain the formula for the angle between two lines using the slopes

Get yourselves a girl who looks at you the same way Prime Newtons looks at his camera when there's an earthquake XD

Some day I gotta meet you and thank for you for inpsiring my mathematical passion!!!!!

Its called a math quake. It happens when chalk rubs harshly against the chalkboard when one gets too excited about doing math.

[@johnroberts7529]

Your lessons are so beautifully constructed and delivered. Great stuff! Please keep making them.

[@stvp68]

Your chalkboard handwriting is so pretty. I wish mine was that nice!

i was just trying to derive the formula and this video came up couple of minutes later, though ur proof is easier to understand😂

Orthogonal lines have m₂ = -1/m₁, hence denominator is zero, so we have arctangent of infinity/undefined. 😉

Very interesting, never happened to see this formula inferred
