Epsilon is as significant as infinity. Is the bracketing [in, oo ...
It includes all positive Real numbers - i.e. Real numbers greater than 0. However, it does not include all positive numbers in bar (RR). For example, it does not include epsilon/2. Note that the interval [epsilon, 1/epsilon] is well defined in bar (RR) and also includes all positive Real numbers.
Find all real numbers in interval [0,2π)? sin x cos (π/4 ... - Socratic
Here put in #y= {\pi}/ {4}# and #\sin (x+y)= {1}/ {2}#. Then we have the following possibilities: (1) #x+ {\pi}/ {4}= {\pi}/ {6}+2m\pi# (2) #x+ {\pi}/ {4}= {5\pi}/ {6 ...
Why is the vertical asymptote for f (x)=sqrt ( (x-3)/x) x=0 when the ...
See below. Vertical asymptotes occur where the function is undefined. In this case at bb (x=0). This give division by zero. If we take the left and right limits as x approaches zero: lim_ (x->0^+)sqrt ( (x-3)/x) undefined for real numbers. lim_ (x->0^-)sqrt ( (x-3)/x)=oo ? ? This confirms an asymptote at x=0. as x approaches 3: lim_ (x->3^+)sqrt ( (x-3)/x)=0 lim_ (x->3^-)sqrt ( (x-3)/x ...
How do you find the domain of #f (x)=3/ (x-4)#? - Socratic
In order for f(x) to be defined you need the denominator not equal to zero. Hence D_f=R-{4} where R is the set of real numbers
What is the range of 20x+4? - Socratic
Because there are no restrictions on the value of x AND because this is a linear transformation: The Range is the set of all Real Numbers or {RR}
How do you find the domain and range of g(t) = 5t? | Socratic
See explanation. Domain The domain is the largest subset of real numbers RR for which the function is defined. To find it we have to look for any possible values of x for which the function is undefined. The possible exclusions are: zeroes of denominators, values for which expressions under square root sign (or other roots with an even degree) are negative values for which expressions under ...
For which values of x element of the real numbers lays the ... - Socratic
For which values of x element of the real numbers lays the graph of the function f with function rule f (x) = 2x^4 + 2x^2 below the graph of the function g with function rule g (x) = 5x^3 + 5x?
Question #129e0 - Socratic
(-oo,oo) ; (-oo, 1)uu(1,oo) ; [-2,oo) The domain of an equation is the possible numbers on the denominator that allow the equation to make sense - making sure you never divide by zero. Therefore we need to look at where the denominator may equal 0. x^2 + 5 = 0. Start off by solving by zero x^2 = -5 Then take the square root x = sqrt(-5) This is impossible therefore the Domain is all real ...
How do you prove #\sec ( - \theta ) + \cot ( \frac { \pi } { 2 ...
The conjugate of x + y is x − y, where x and y are real numbers. If y is imaginary, the process is termed complex conjugation: the complex conjugate of a + bi is a − bi, where a and b are real. Tip - Solving or proving trigonometric identities is a lot more similar to algebraic identities than you think!
