cos (arctan (3) - arcsin (\frac{3}{2}))

Rewrite using trig identities:

cos (arctan (3)) cos (arcsin (\frac{3}{2})) + sin (arctan (3)) sin (arcsin (\frac{3}{2}))

cos (arctan (3) - arcsin (\frac{3}{2}))

cos (s - t) = cos (s) cos (t) + sin (s) sin (t)

:فعّل متطابقة الطرح لزوايا

= cos (arctan (3)) cos (arcsin (\frac{3}{2})) + sin (arctan (3)) sin (arcsin (\frac{3}{2}))

= cos (arctan (3)) cos (arcsin (\frac{3}{2})) + sin (arctan (3)) sin (arcsin (\frac{3}{2}))

Rewrite using trig identities:

cos (arctan (3)) = \frac{1}{2}

cos (arctan (3))

Rewrite using trig identities:

cos (arctan (3)) = \frac{1 + ( 3 ) ^{2}}{1 + ( 3 ) ^{2}}

cos (arctan (x)) = \frac{1 + x ^{2}}{1 + x ^{2}} :

استخدم المتطابقة التالية

= \frac{1 + ( 3 ) ^{2}}{1 + ( 3 ) ^{2}}

= \frac{1 + ( 3 ) ^{2}}{1 + ( 3 ) ^{2}}

Rewrite using trig identities:

cos (arcsin (\frac{3}{2})) = \frac{1}{2}

cos (arcsin (\frac{3}{2}))

Rewrite using trig identities:

cos (arcsin (\frac{3}{2})) = 1 - (\frac{3}{2})^{2}

cos (arcsin (x)) = 1 - x^{2} :

استخدم المتطابقة التالية

= 1 - (\frac{3}{2})^{2}

= 1 - (\frac{3}{2})^{2}

sin (arctan (3))

Rewrite using trig identities:
