We know that
<span>sec a = 5/4
</span>sec(a)=1/cos(a)
then
cos (a)=1/sec(a)
cos (a)=1/(5/4)=4/5---> is positive because the function cos is positive in IV quadrant
the answer is cos(a)=4/5
y=∣x−1∣={
1−x
x−1
x<1
x≥1
}
Similarly y=3−∣x∣={
3+x
3−x
x<0
x≥0
}
The required region is a rectangle with length 2
2
and breadth
2
.
Hence, the area is 4. Hence, all the options are correct
