d²y/dx² = -CotyCosec²y यदि y = Cos⁻¹x
Step-by-step explanation:
d²y/dx² केवल y के पदों में ज्ञात कीजिए
y = Cos⁻¹x
Cosy = x
-Siny (dy/dx) = 1
dy/dx = -1/Siny
d²y/dx² = (-1(-1)/Sin²y)Cosy*dy/dx
=> d²y/dx² = (Cosy/Sin²y)dy/dx
=> d²y/dx² = (Cosy/Sin²y)(-1/Siny)
=> d²y/dx² = -Coty/Sin²y
=> d²y/dx² = -CotyCosec²y
