Question

Y×sin45×cos45=tan^245-cos^230=

Answer 1

Answer:

$y = \frac{1}{2}$

Step-by-step explanation:

$y \times \sin(45) \times \cos(45) = { \tan(45) }^{2} - { \cos(30) }^{2} \\ y \times \frac{1}{ \sqrt{2} } \times \frac{1}{ \sqrt{2} } = 1 - {( \frac{ \sqrt{3} }{2} )}^{2} \\ \frac{y}{2} = 1 - \frac{3}{4} \\ y = 2( \frac{1}{4} ) \\ y = \frac{1}{2}$

Answer 2

$\frac{1}{2}$
