( 5 sin ø - 3 cos Ø )
________________
sin Ø + 2 cos Ø
=> 5 - 3 cot ∅
( ___________ )
1 + 2 cot ∅
=>. 5 - 3 × 4
[ ____. ]
5
________________
1 + 2 x 4

= 1
2 - ) ( b sin Ø - a cos Ø)
_______________
b sin Ø+ a cos Ø
SOLUTION
( b sin Ø - a cos Ø)
_______________
b sin Ø+ a cos Ø
= ( b tan Ø - a )
____________
( b tan Ø+ a )
b
= b × ___ - a
a
__________. (:. tan Ø= b /a
b
b × ___. + a
a
= b ² - a ²
________
b² + a ²
Choose the most appropriate unit to measure the weight of each.
