(b) (3-4sin sqr theta).(sec sqr theta-4tan sqr theta)=(3-tan sqr theta). (1-4sin sqre theta) (c) (3-4sin^ A). (1-3tan^ A)=(3-tan^A) = (4cos^A-3)
(d) (3-4 cos^A). (cosec^A-4cot^A) = (3-cot^A). (1-4 cos^A)
(e) sec to the power 4 A (1-sin to the power 4 A) - tan^A=1

2/5

step-by-step explanation:

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93

i am not sure
