Question

If tano +seco =4then find sino?​

Answer 1

$\mathfrak \red{given :tan \theta + sec \theta = 4 } \\ \mathfrak{too \: find :sin \theta } \\ \frac{sin \theta}{cos \theta} + \frac{1}{cos \theta} \\ \frac{sin \theta + 1}{cos \theta} = 4 \\ sin \theta + 1 = 4co s \theta \\ sin \theta = 4cos \theta - 1$

Hope my answer will help you...
