Venus and her cousin Ursula recently celebrated their birthdays on the same Sunday in December 2021. Ursula is now four times as

AnnZ [28]

The date are given by the expressing the given information as functions,

and evaluating based on the constraints.

Response:

Venus is 15 years, and Ursula is likely 24 years old

Venus is likely born on a Thursday

<h3>How can the ages and date of birth be calculated?</h3>

Let x represent the number of years age when Ursula's age was the

same as Venus's age now and let y represent the age of Venus, we

have;

Ursula's age = y + x = 4 × (y - x)

y > 12

Which gives;

y + x = 4 × (y - x) = 4·y - 4·x

y + x = 4·y - 4·x

5·x = 3·y

$y = \dfrac{5}{3} \cdot x$

y, and x are whole numbers, which gives;

When x = 9

$Venus's \ age \ y = \dfrac{5}{3} \times 9 \, years =\underline{ 15 \, years}$

Ursula's age = 15 years + 9 years = 24 years

From the calendar, we have;

Sundays in December 2021 includes the 7th, 14th, 11st and 28th of

December

The year Venus is born = 2021 - 15 = 2006 Calendar

7th, 14th, 11st and 28th of December 2006 are on Thursdays

Therefore;

Venus was born on a Thursday

Below is an attempt to derive the derivative of sec(x) using product rule, where x is in the domain of secx. In which step, if a

4vir4ik [10]

The error occurs in step 3. By the product rule, we have

$\dfrac{\mathrm d}{\mathrm dx}(\sec x\times\cos x)=\dfrac{\mathrm d}{\mathrm dx}(\sec x)\times\cos x+\sec x\times\dfrac{\mathrm d}{\mathrm dx}(\cos x)$

$=\dfrac{\mathrm d}{\mathrm dx}(\sec x)\times\cos x\boxed{+\sec x\times(-\sin x)}$

$=\dfrac{\mathrm d}{\mathrm dx}(\sec x)\times\cos x\boxed{-\sec x\times\sin x}$

(i.e. there is a missing factor of $\sin x$ )

Then

$\dfrac{\mathrm d}{\mathrm dx}(\sec x)\times\cos x-\sec x\times\sin x=0$

$\implies\dfrac{\mathrm d}{\mathrm dx}(\sec x)\times\cos x=\sec x\times\sin x$

$\implies\dfrac{\mathrm d}{\mathrm dx}(\sec x)=\dfrac{\sec x\times\sin x}{\cos x}$

$\implies\dfrac{\mathrm d}{\mathrm dx}(\sec x)=\sec x\times\tan x$
