( cos x - sin x )^ 2 = 1- sin 2 x |
|
Answer» Answer: It depends on how far back you need to go in your proof. If you can use: sin 2 ( x ) + 2 ( x ) = 1 (which can be derived from the Pythagorean Theorem) and sin ( 2 x ) = 2 sin ( x ) ⋅ cos ( x ) (the Double Angle FORMULA for sin, which is considerably more complicate to prove) then the REQUESTED proof is fairly SIMPLE: ( sin ( x ) + cos ( x ) ) 2
= sin 2 ( x ) + 2 sin ( x ) ⋅ cos ( x ) + cos 2 ( x )
= [ sin 2 ( x ) + cos 2 ( x ) ] + 2 sin ( x ) ⋅ cos ( x )
= 1 + sin ( 2 x ) |

how many bricks are required to build a wall 15 m long 3 m high and 50 cm thick ,if each brick measures 25 cm by 12 cm by 6 cm? |
|
Answer» Answer: 6250 Step-by-step EXPLANATION: Measurement of the WALL Length of wall= 15m =15×100 =1500 Height of wall = 3M = 3× 100 =300 Thickness of wall= 25 Volume of wall = length × breath × height 1500 × 300 × 25
= 11250000
Measurement of brick Length= 25, breadth=12 and height=6 Volume of brick = 25 × 12 × 6 = 1800 Total no of bricks = volume of wall ÷ volume of 1 brick 11250000÷1800 = 6250 |

Iii) Prove that Tan 72° = Tan 18° + 2 Tan 54 degrees |
|
Answer» Step-by-step explanation: we have to PROVE that tan72 ° = tan18 ° + 2tan54 ° [ you did mistake in typing ] we know , tan ( A - B ) = ( tanA - TANB ) / ( 1 + tanA . tanB ) tan54 ° = tan ( 72 ° - 18 ° ) or , tan54 ° = ( tan 72 ° - tan18 ° ) / ( 1 + tan72 ° . tan189 ) or , tan54 ° ( 1 + tan72 ° . tan18 ° ) = tan72 - tan18 ° we know , tan72 ° = tan ( 90 ° - 18 ° ) = COT18 ° or , tan54 ° ( 1 + cot18 ° . tan18 ° ) = tan 72 ° - tan18 ° or , tan54 ° ( 1 + 1 ) = tan 72 ° - tan18 ° or , 2tan54 ° = tan 72 ° - tan18 ° hence , tan72 ° = tan18 ° + 2tan54 LHS = RHS |
