2. ### I Algebra equation with variable as exponent

I It is just a random picture. Newton's method can be punched into an excel spreadsheet? How?
3. ### I Algebra equation with variable as exponent

This equation takes a present value (PV) to find mortgage payments, PMT: Alternatively, switching V for PV and T for PMT: V/T = r(1-r^n)/(1-r) What is an algebraic method to solve for "r"? Can it not be solved for? I realize I can just find out "r" by trial by error in Excel using the PMT...
4. ### B What's the equation for an I Bond? (compounded semi-annually)

For first 6 months: I = PRT. Interest = ($10,000) * (3.54%) * (0.5 years) =$177. For next 6 months: I = PRT. Interest = ($10,177) * (7.12%) * (0.5 years) =$362. 10000(1+[0.5*3.54%+(1+3.54%*0.5)*7.12%*0.5]) = Ending balance = $10,177 +$362 = $10,539.$1000*9%*0.5 = afterSix = 45...

48. ### TTL, voltage, one-wire test rig

The GPIO pins were chosen out of house. An electrician, in house, who wired the rest of data logger board (flexs Q4) just wired the GPIO pins it how they told him. And now they tasked me, an EE student, with the project of creating a test rig. The pins that are connected use the following...
49. ### TTL, voltage, one-wire test rig

Digital Storage Oscilloscope? So you're saying that buying the handheld oscilloscope is a good idea? I do not have access to uC dev board. I also do not know what that is. My emphasis is not computers. I know every little about protocols (for the one-wire sensor).
50. ### TTL, voltage, one-wire test rig

Spec My job, as an undergraduate EE student, is to create a test rig for offsite electronics (environmental sensors hooked up to a data logger, 12V batteries and solar panels). The test rig should be able to evaluate output from sensors (serial TTL, analog voltage, 1-wire) and output required...
