1 mile = about 1  1/3 km because 8/6  = 1 1/3
so 28 times 1 1/3 = 37 1/3  (first answer)

42 / 6 = 7 
7 miles are in 42 km (2nd answer)

If you're just starting calculus, perhaps you're asking about using the definition of the derivative to differentiate x^4.

We have

\dfrac{d}{dx} x^4 = \displaystyle \lim_{h\to0} \frac{(x+h)^4 - x^4}h

Expand the numerator using the binomial theorem, then simplify and compute the limit.

\dfrac{d}{dx} x^4 = \displaystyle \lim_{h\to0} \frac{(x^4+4hx^3 + 6h^2x^2 + 4h^3x + h^4) - x^4}h \\\\ ~~~~~~~~ = \lim_{h\to0} \frac{4hx^3 + 6h^2x^2 + 4h^3x + h^4}h \\\\ ~~~~~~~~ = \lim_{h\to0} (4x^3 + 6hx^2 + 4h^2x + h^3) = \boxed{4x^3}

In general, the derivative of a power function f(x) = x^n is \frac{df}{dx} = nx^{n-1}. (This is the aptly-named "power rule" for differentiation.)

If the angles are represented in degrees,find both angles: csc(2x+9) =sec(3x+26) Please respond quick
Olenka [21]

Answer:

Before solving the given trigonometric relation change everything to sines and cosines

Step-by-step explanation:

consider the given equation;

1/sin(2x+9)=1/cos(3x+26)

Multiplying the above equation on both sides by cos(3x+26)sin(2x+9) then we get,

cos(3x+26)=sin(2x+9)

By using identity,cos a=sin(90-a) expand above equation we will get,

sin(90-(3x+26))=sin(2x+9)

Then,

90-3x+26=2x+9

x=11

So the required value of the angle is 11 degree.
