Ex 6.3, 1 Find the slope of the tangent to the curve ๐‘ฆ=3๐‘ฅ4 โ€“ 4๐‘ฅ ๐‘Ž๐‘ก ๐‘ฅ= 4 ๐‘ฆ=3๐‘ฅ4 โ€“ 4๐‘ฅ We know that slope of tangent =๐‘‘๐‘ฆ/๐‘‘๐‘ฅ =3.4๐‘ฅ^(4โˆ’1)โˆ’4 =12๐‘ฅ^3โˆ’4 So, ๐‘‘๐‘ฆ/๐‘‘๐‘ฅ=12๐‘ฅ^3โˆ’4 Putting ๐‘ฅ=4 (๐‘‘๐‘ฆ/๐‘‘๐‘ฅ)_(๐‘ฅ = 4)=12(4)^3โˆ’4 =768โˆ’4 =764 Thus, Slope of the tangent is 764 at ๐‘ฅ=4
