Use Pythagoras' theorem of: a2+b2 = c2 whereby a and b are the sides of the triangle with c being its hypotenuse
ln 1 = 0 e0=1
It is equal to 0
You can calculate log to any base by using: logb(x) = ln(x) / ln(b) [ln is natural log], so if you have logb(e) = ln(e) / ln(b) = 1 / ln(b)
Because of the commutative property of addition.
Assuming you mean 'logarithm to the base 'e' ( natural logarithm. On the calculator its symbol is 'ln'. Hence ;ln 2 = 0.69314718....
pi2
e = 2.71828183 (approximately)The definition of ln is this: ln x = y when e ^ y = x. It's an inverse property... So ln x means "find out what value y would need to have so that e ^ y equals x" Since e ^ 1 = e, ln e has to equal 1. because in line equation to signify that the task/job is done. This is why it is equal to 1.cause you add them and it just does
ln(1.45) is roughly equal to the decimal approximation 0.371563556432.
so, if 2 minus Ln times 3 minus x equals 0, then 2 minus Ln times 3 equals x, therefore 2 minus Ln equals x divided by three, so Ln + X/3 = 2 therefore, (Ln + [X/3]) = 1
A "30 60 90 triangle" has that weird name because those numbers are its three angles. It can't have any angle of "4". If a triangle has an angle of '4', then it's not a '30 60 90 triangle'.
Ln 4 + 3Ln x = 5Ln 2 Ln 4 + Ln x3= Ln 25 = Ln 32 Ln x3= Ln 32 - Ln 4 = Ln (32/4) = Ln 8= Ln 2
log(2) = X can be expressed exponentially like this, because by the definition of logs( base 10) this is what this means. 10^X = 2 take natural log each side ln(10^X) = ln(2) you have right to place X in front of ln X ln(10) = ln(2) X = ln(2)/ln(10) ( not ln(2/10)!! ) X = 0.3010299957 check 10^0.3010299957 = 2 checks
