In summary, to calculate manually without using MATLAB, you can use basic math principles such as addition, subtraction, multiplication, and division, as well as a calculator if needed. Some common math problems that can be solved manually include calculating percentages, finding the area and perimeter of shapes, solving equations, and converting measurements. You can also get help from a Pampered Chef consultant or use online resources, textbooks, or ask for assistance from others. Learning how to calculate manually is important as it helps improve critical thinking, problem-solving skills, and a deeper understanding of mathematical concepts.

Can someone help me with this? You don't need to do MATLAB, just compute manually.

Have you calculated T(x)? You are given $y^4+ xy= 2x^2- 7x+ 7$. Differentiating, $4y^3\frac{dy}{dx}+ y+ x\frac{dy}{dx}= 4x- 7$. $4y^3\frac{dy}{dx}+ x\frac{dy}{dx}= (4y^3+ x)\frac{dy}{dx}= 4x- y- 7$. $\frac{dy}{dx}= \frac{4x- y- 7}{4y^3+ x}$. At (1, 1), $\frac{dy}{dx}= \frac{4- 1- 7}{4+ 1}= \frac{-4}{5}$. $T(x)= -\frac{4}{5}(x- 1)+ 1= -\frac{4}{5}x+ \frac{1}{5}$.
