Example 14 Find the slope of the tangent to the curve ð¦ = ð¥3 â ð¥ at ð¥ = 2. We know that Slope of tangent = ï·ðð¦ï·®ðð¥ï·¯ =ï·ðï·ï·ð¥ï·®3ï·¯â ð¥ï·¯ï·®ðð¥ï·¯ =3ï·ð¥ï·®2ï·¯â1 So, ï·ðð¦ï·®ðð¥ï·¯=3ï·ð¥ï·®2ï·¯â1 Putting x = 2 ï·ï·ï·ðð¦ï·®ðð¥ï·¯ï·¯ï·®ð¥=2ï·¯=3ï·ï·2ï·¯ï·®2ï·¯â1 =3ï·4ï·¯â1=12â1=11 Thus, slope of the tangent is 11
