►For

**algebraic problems**where you need to find

**the exact value of a dependent or independent variable**, just use the

**CALC**or

**[ES] Mode 5 functions**or

**[EX] MENU A functions**.

►For

**definite differentiation and integration problems**, simply use the

**d/dx and integral operators**in the

**COMP mode**.

►For models that

**follow the differential equation: dP/dx=kt**and models that

**follow a geometric function(i.e. A*B^x)**.

**[ES]**

**-Simply go to Mode 3 (STAT) (5) e^x**

**-For geometric functions Mode 3 (STAT) 6 A*B^x**

**-(Why? Because the solution to the D.E. dP/dx=kt is an exponential function e^x.**

**When we know the boundary con…**
