Which row operation will triangularize this matrix?
Ludmilka [50]
Triangularizing matrix gives the matrix that has only zeroes above or below the main diagonal. To find which option is correct we need to calculate all of them.
In all these options we calculate result and write it into row that is first mentioned:

A)R1-R3
\left[\begin{array}{ccc}-1&0&0|0\\0&1&1|6\\2&0&1|1\end{array}\right]

B)2R2-R3
\left[\begin{array}{ccc}1&0&1|1\\-2&2&1|4\\2&0&1|1\end{array}\right]

C)-2R1+R3
\left[\begin{array}{ccc}0&0&-1|-1\\0&1&1|6\\2&0&1|1\end{array}\right]

D)2R1+R3
\left[\begin{array}{ccc}4&0&3|3\\0&1&1|6\\2&0&1|1\end{array}\right]

E)3R1+R3
\left[\begin{array}{ccc}5&0&4|4\\0&1&1|6\\2&0&1|1\end{array}\right]

None of the options will triangularize this matrix. The only way to <span>triangularize this matrix is
R3-2R1
</span>\left[\begin{array}{ccc}1&0&1|1\\0&1&1|6\\0&0&-1|-1\end{array}\right]
<span>
This equation is similar to C) but in reverse order. Order in which rows are written is important.</span>

Find cos θ if csc θ = 2 and θ is in quadrant II.
natita [175]
Cosecant is one of the six trigonometric identities which is equal to the reciprocal of sine function. In this case, theta is equal to sin -1 = 1/2 equal to 30 degrees. Since this is in quadrant II, the angle is 180 - 30 or 150 degrees. cos 150 is equal to -0.866 or -ssqrt 3 over 2.
