Solve the equation for

OR


If prove that

To solve for x: sin-1 x + sin-1 (1 – x) = cos-1 x


Let cos-1 x = θ


⇒ x = cos θ


We know,





We have,


sin-1 x + sin-1 (1 – x) = cos-1 x


Put cos-1 x = θ:


⇒ sin-1 x + sin-1 (1 – x) = θ



















OR









Squaring both sides:










Hence Proved

There are two types of fertilizers ‘A’ and ‘B’. ‘A’ consists of 12% nitrogen and 5% phosphoric acid whereas ‘B’ consists of 4% nitrogen and 5% phosphoric acid. After testing the soil conditions, farmer finds that he needs at least 12 kg of nitrogen and 12 kg of phosphoric acid for his crops. If ‘A’ costs ₹ 10 per kg and ‘B’ cost ₹ 8 per kg, then graphically determine how much of each type of fertilizer should be used so that nutrient requirements are met at a minimum cost.
