Hi there!
ln(-1) = e ^(i*Pi) FALSE, because e^(ipi) = -1
2/3 + 3/4+ 4/5 = 133/60 TRUE, by adding
e^(i*x) = cos(x) + (i)^3 * sin (x) FALSE (it's i, not i^3)
The equation above can have X expressed in either radians or degrees FALSE
A/B + C/D = ( A*D + C* B ) / (B*D)
AD/BC + CB/DB = (AD+CB)/BD TRUE
If I can do long division, then I should be able to divide two polynomials
TRUE (it's the same process)
In any triangle where the Pythagorian Theorem is true means that one of the included angles must be = Pi/2 radians TRUE (90 degree angle)
1/0 = infinitiy TRUE (it's undefined)
Absolute value of [ A + iB] = (A^2 + B^2)^ (1/2)
TRUE , by Pythagorean Theorem
e^X never intersects X^ 3 FALSE
There a real value for X where e^X < 0 FALSE
Let me know if you have any questions,
Scott
