Answer:

cot(theta) = 1/(-3/8)

Step-by-step explanation:

cot(theta) = 1/tan(theta) = 1/(-3/8)

_____

<em>Comment on the answer</em>

The parentheses are required. With them, the value is cot(theta) = -8/3. Without them, the value is cot(theta) = -1/24, which is not correct.

Even if the answer is typeset, it must be done in such a way as to make it clear what the numerator and denominator are:

$\displaystyle\frac{1}{-\frac{3}{8}}$

Verify the identity: (1-sinx)/cosx = cosx/(1+sinx)

Tresset [83]

Cross multiply the expression so that we can get

(1+sinx)(1-sinx) = cos^2 x

1 - sin^2 x = cos^2 x

cos^2 x + sin^2 x = 1

since

cos^2 x + sin^2 x = 1

therefore

1 = 1

the two expressions are identical in a trigonometric sense

Value of this problem?

Rudik [331]

$\frac{4^3\times4^{-1}\times5^{-2}}{4^4\times5^{-3}\times5^0}=\frac{4^{3-1}\times5^{-2}}{4^4\times5^{-3+0}}\\=\frac{4^{2}\times5^{-2}}{4^4\times5^{-3}}=4^{2-4}\times5^{-2-(-3)}\\=4^{-2}\times5^{1}=\frac{5}{4^2}\\=\frac{5}{16}$
