Subtract.<br> (6-v-25) - (7+-4)

dmitriy555 [2]

Answer:

$\left(6-v-25\right)-\left(7+\left(-4\right)\right)=-v-22$

Step-by-step explanation:

Considering the expression

$\left(6-v-25\right)\:-\:\left(7+-4\right)$

$\left(6-v-25\right)-\left(7+\left(-4\right)\right)$

$\mathrm{Remove\:parentheses}:\quad \left(a\right)=a$

$6-v-25-\left(7-4\right)$

$\mathrm{Subtract\:the\:numbers:}\:7-4=3$

$6-v-25-3$

$\mathrm{Group\:like\:terms}$

$-v+6-25-3$

$\mathrm{Add/Subtract\:the\:numbers:}\:6-25-3=-22$

$-v-22$

Therefore,

$\left(6-v-25\right)-\left(7+\left(-4\right)\right)=-v-22$

It's not difficult to compute the values of $A$ and $B$ directly:

$A=\displaystyle\int_1^{\sin\theta}\frac{\mathrm dt}{1+t^2}=\tan^{-1}t\bigg|_{t=1}^{t=\sin\theta}$
$A=\tan^{-1}(\sin\theta)-\dfrac\pi4$

$B=\displaystyle\int_1^{\csc\theta}\frac{\mathrm dt}{t(1+t^2)}=\int_1^{\csc\theta}\left(\frac1t-\frac t{1+t^2}\right)\,\mathrm dt$
$B=\left(\ln|t|-\dfrac12\ln|1+t^2|\right)\bigg|_{t=1}^{t=\csc\theta}$
$B=\ln\left|\dfrac{\csc\theta}{\sqrt{1+\csc^2\theta}}\right|+\dfrac12\ln2$

Let's assume $0$ , so that $|\csc\theta|=\csc\theta$ .

Now,

$\Delta=\begin{vmatrix}A&A^2&B\\e^{A+B}&B^2&-1\\1&A^2+B^2&-1\end{vmatrix}$
$\Delta=A\begin{vmatrix}B^2&-1\\A^2+B^2&-1\end{vmatrix}-e^{A+B}\begin{vmatrix}A^2&B\\A^2+B^2&-1\end{vmatrix}+\begin{vmatrix}A^2&B\\B^2&-1\end{vmatrix}$
$\Delta=A(-B^2+A^2+B^2)-e^{A+B}(-A^2-A^2B-B^3)+(-A^2-B^3)$
$\Delta=A^3-A^2-B^3+e^{A+B}(A^2+A^2B+B^3)$

There doesn't seem to be anything interesting about this result... But all that's left to do is plug in $A$ and $B$ .
