Equation of a Tangent and Normal to a Circle - Lesson 4 | SHS 1 ELECTIVE MATH

TOPIC: Equation of a Tangent and Normal to a Circle - Lesson 4 In this video, we are going to learn how find 1. the equation of the tangent to a circle 2. the normal of the tangent to a circle A tangent is a straight line that just touches the circle at a point on the circumference, and this tangent line is perpendicular to the line drawn from the center of the circle to the point of contact, called the radius. let gradient of the radius be m1 and gradient of the tangent be m2 m1(m2) = -1, therefore y-y1 = m2(x-x1) The normal line is the line that is perpendicular to the tangent. Also for the normal m1 = m2 y-y1 = m2(x-x1) Subscribe to @Skancityacademy on youtube Check out my playlist on Senior High School (Maths)    • Senior High School (Maths)   Whatsapp: +233 (0) 243084034 Instagram: sir_john_skancityacademy
